Fiona is a UR Missile Vehicle damage dealer in Last War Survival who specializes in Physical Damage and full-team attacks. Her Atomic Blast Tactic skill can damage every enemy in the formation, while Ballistic Boost increases her Physical Damage throughout the battle. This guide covers Fiona’s skills, upgrade priority, gear, positioning, Missile team composition, Wall of Honor bonus, and Season 5 Exclusive Weapon.
Fiona Hero Overview
Fiona, also known as the Lion Cub, is built to function as a back-row damage dealer. Unlike heroes who focus on one target, her Tactic skill attacks the full opposing formation, making her useful when several enemies need to be damaged at the same time.
- Rarity: Ultra Rare (UR)
- Vehicle Type: Missile Vehicle
- Specialty: Damage Dealer
- Damage Type: Physical Damage
- Listed March Size: 350
- Main Role: Full-team Physical Damage and Missile squad offense
Fiona benefits from the statistics provided by the Missile Center. Upgrading this building improves the Attack, HP, Defense, and March Size of eligible Missile Vehicle heroes.
Fiona Reference Stats
| Stat | Reference Value |
|---|---|
| Attack | 23.6K |
| HP | 400.2K |
| Defense | 2.9K |
| March Size | 350 |
Important Note: These are reference values from the supplied hero information. Fiona’s actual statistics depend on her level, stars, skills, gear, Missile Center, research, Drone, decorations, Exclusive Weapon, and other account bonuses.
Fiona’s Strengths and Weaknesses
Main Strengths
- Full-team Tactic damage: Atomic Blast attacks every enemy in the opposing formation.
- Strong Physical Damage scaling: Ballistic Boost increases Fiona’s Physical Damage throughout the battle.
- Frequent auto attacks: Double Trajectory has a listed cooldown of 1.35 seconds.
- Missile formation synergy: Fiona benefits from Missile Center upgrades, Missile research, and full Missile squad bonuses.
- Powerful Exclusive Weapon: Her Season 5 weapon adds Radiation and can remove enemy buffs.
- Useful in multi-target combat: Her full-team Tactic is relevant when several enemy heroes remain active.
Main Weaknesses
- Limited frontline durability: Fiona should not normally be used as a Defender.
- Requires protection: She needs durable heroes in the front row to remain active.
- High investment requirements: Her strongest results require stars, skills, gear, research, and later an Exclusive Weapon.
- Limited direct support: Her base kit focuses on damage rather than healing or squad protection.
- Late weapon availability: Her Exclusive Weapon is connected to Season 5 progression.
Fiona’s Skills Explained
Double Trajectory

Double Trajectory is Fiona’s auto-attack skill. It fires an anti-aircraft missile and deals Physical Damage equal to 408.11% of Fiona’s Attack.
- Type: Auto Attack
- Cooldown: 1.35 seconds
- Damage Type: Physical Damage
- Main Purpose: Consistent damage between Atomic Blast casts
The listed star effects improve its additional damage:
- First listed star effect: +30% additional damage.
- Second listed star effect: increases additional damage to 70%.
- Third listed star effect: increases additional damage to 120%.
- Fourth listed star effect: increases additional damage to 185%.
- Fifth listed star effect: increases additional damage to 270%.
The phrase “anti-aircraft missile” appears in the skill description, but it should not automatically be interpreted as a separate bonus against Aircraft heroes. Fiona already benefits from the standard Missile Vehicle counter relationship when fighting Aircraft formations.
Double Trajectory should normally be Fiona’s second Skill Medal priority after Atomic Blast.
Ballistic Boost

Ballistic Boost is Fiona’s passive skill. Its listed base effect increases her Physical Damage by 30% during battle.
- Type: Passive
- Cooldown: None
- Main Purpose: Increasing the damage produced by Fiona’s attacks
Each listed star effect adds another 3 percentage points to the bonus. With all five listed increments, star progression contributes up to 15 additional percentage points.
Ballistic Boost affects Fiona throughout the battle, making it an important part of her damage. However, it is generally upgraded after Atomic Blast and Double Trajectory because those two skills directly determine the damage multipliers of her attacks.
Keep Ballistic Boost within a reasonable level range instead of leaving it permanently underdeveloped. As the first two skills become expensive, lower-cost passive upgrades may provide efficient value.
Atomic Blast

Atomic Blast is Fiona’s main Tactic skill. It fires a rocket that attacks every enemy, with each hit dealing Physical Damage equal to 718.17% of Fiona’s Attack.
- Type: Tactic Skill
- Cooldown: 10 seconds
- Damage Type: Physical Damage
- Main Purpose: Full-team damage
The listed star effects increase its additional damage:
- First listed star effect: +30% additional damage.
- Second listed star effect: increases additional damage to 70%.
- Third listed star effect: increases additional damage to 120%.
- Fourth listed star effect: increases additional damage to 185%.
- Fifth listed star effect: increases additional damage to 270%.
Atomic Blast is normally Fiona’s highest Skill Medal priority because it attacks the entire enemy formation and provides her most important burst-damage effect.
Players cannot usually activate Atomic Blast manually during normal automated battles. The original advice to time it against grouped enemies was misleading because the game controls its activation and it already targets the full enemy formation.
Super Sensing

Super Sensing is Fiona’s Expertise effect. It provides the following listed bonuses:
- Fiona’s HP +20%.
- Fiona’s Attack +20%.
- Fiona’s Defense +20%.
- Skill cooldown rate +10%.
The additional Attack supports her damage, while HP and Defense help her survive longer in the back row. The cooldown-rate bonus also allows her skills to activate more frequently.
Super Sensing is not a standard Skill Medal upgrade. It uses separate Expertise progression and should not be included as the fourth entry in Fiona’s normal skill-upgrade order.
Fiona Skill Upgrade Priority
Fiona generally follows the standard Attacker priority:
- Atomic Blast
- Double Trajectory
- Ballistic Boost
- Super Sensing through separate Expertise progression
| Priority | Skill | Reason |
|---|---|---|
| 1 | Atomic Blast | Attacks the entire enemy formation and provides Fiona’s main burst damage |
| 2 | Double Trajectory | Provides frequent Physical Damage between Tactic casts |
| 3 | Ballistic Boost | Passively increases all Physical Damage but does not create another attack |
| Separate | Super Sensing | Expertise effect rather than a standard Skill Medal upgrade |
A practical progression pattern is:
- Raise Atomic Blast to the next useful milestone.
- Keep Double Trajectory approximately five levels behind.
- Keep Ballistic Boost within another five to ten levels when Skill Medals allow.
- Return to Atomic Blast when lower-priority upgrades become less efficient.
This is a flexible guideline rather than a strict rule. Ballistic Boost may deserve additional levels when its next upgrade is much cheaper than Atomic Blast and provides a useful increase to all of Fiona’s Physical Damage.
For broader planning across hero roles, review the Last War hero skill upgrade priority guide.
Best Position for Fiona
Fiona should normally be placed in the back row. Her main role is to remain alive and cast Atomic Blast repeatedly, not to absorb frontline attacks.
A standard formation structure uses:
- Front row: Two durable Defenders.
- Back row: Fiona, another damage dealer, and a third Attacker or Supporter.
Keeping Fiona protected allows her to:
- Cast Atomic Blast more than once in longer battles.
- Continue using Double Trajectory throughout the fight.
- Benefit from Ballistic Boost for the full battle duration.
- Apply Radiation repeatedly after unlocking her Exclusive Weapon.
Fiona should only be moved forward in a specialized formation with enough defensive support and equipment. For most accounts, frontline placement reduces her damage by causing her to be defeated too early.
Best Missile Team for Fiona
Fiona performs best in a developed Missile Vehicle formation. A full Missile squad supports troop-type bonuses, Missile Center statistics, Missile research, and the later team bonus from her Exclusive Weapon.
Full Missile Formation
| Position | Suggested Heroes |
|---|---|
| Front Row | Adam and McGregor |
| Back Row | Fiona, Tesla, and Swift |
In this formation:
- Adam and McGregor protect the back row.
- Fiona damages the full opposing formation.
- Tesla provides additional Missile damage.
- Swift attacks several enemies and helps finish weakened targets.
The strongest lineup depends on hero stars, skills, gear, Exclusive Weapons, and season progression. A highly developed mixed hero may perform better than a low-star Missile replacement, even if the mixed squad receives a smaller formation bonus.
Transitional Fiona Formation
Players without a complete premium Missile team can place Fiona behind their two strongest Defenders. Add another developed damage dealer and a useful Supporter until the full Missile lineup is ready.
A transitional team should still include:
- Two heroes capable of protecting the back row.
- At least one additional damage dealer.
- Enough support or control for Fiona to survive through several skill cycles.
Avoid spreading Universal Legendary Hero Shards across every Missile hero at once. Complete Fiona’s important star milestone and maintain a functional frontline before expanding the rest of the formation.
Fiona and Vehicle-Type Matchups
Missile Vehicle formations generally perform better against Aircraft formations and worse against Tank formations. This makes Fiona particularly useful when facing Aircraft-focused opponents of comparable development.
| Opponent Type | General Fiona Matchup |
|---|---|
| Aircraft | Missile formations generally have an advantage |
| Missile | Results depend more heavily on stars, skills, gear, and formation quality |
| Tank | Missile formations generally face a disadvantage |
The vehicle counter does not guarantee victory. A stronger opponent can overcome an unfavorable matchup through better heroes, troops, research, gear, decorations, and Drone development.
Review the Last War troop stats guide to understand how Attack, Defense, HP, and other statistics contribute to combat performance.
Best Gear for Fiona
Fiona is a back-row damage dealer, so her first equipment priorities should normally improve Attack and offensive output.
- Gun: Provides the most direct increase to Fiona’s Physical Damage.
- Data Chip: Supports offensive and critical performance.
- Radar: Helps Fiona survive Energy Damage and skill-heavy opponents.
- Armor: Adds additional durability after the important offensive pieces are developed.
If Fiona is being defeated before casting Atomic Blast enough times, move Radar ahead of Data Chip. Surviving for another Tactic cycle may produce more total damage than a small offensive improvement.
A practical gear strategy is:
- Assign Fiona a strong Gun if she is one of your main damage dealers.
- Prioritize meaningful level and star milestones rather than upgrading every item equally.
- Give the best defensive equipment to frontline heroes first.
- Avoid spending Legendary Blueprints before checking the full promotion requirement.
- Compare Fiona’s investment with Tesla, Swift, and any other main Missile damage dealer.
Use the Last War gear upgrade and promotion guide before spending large amounts of Upgrade Ore, Dielectric Ceramic, or Legendary Blueprints.
Fiona’s Exclusive Weapon
Fiona receives an Exclusive Weapon during Week 1 of Season 5. The listed activation requirements are:
- Fiona must reach 5 stars.
- You need 50 Fiona-specific Exclusive Weapon Shards.
Once activated, the weapon adds Radiation effects and allows Fiona to remove selected buffs from enemy heroes.
| Weapon Level | Effect |
|---|---|
| Level 1 | Double Trajectory applies one Radiation stack to its target |
| Level 10 | Atomic Blast removes a combined total of two hero-applied buff stacks from enemies |
| Level 20 | Missile Specialist increases the Attack, Defense, and HP of all Missile Vehicle heroes by 7.5% |
| Level 30 | Every 20 damage-over-time stacks across all enemies allows Atomic Blast to remove another buff stack, up to five |
Radiation Effect
Radiation deals continuous Physical Damage equal to 5% of Fiona’s Attack every second for 20 seconds.
The maximum number of Radiation stacks on one enemy depends on the number of Missile Vehicle heroes in Fiona’s squad. Each Missile hero supports two possible stacks, up to a maximum of ten.
This gives Fiona’s weapon greater value in a complete five-hero Missile formation. At ten stacks, the target receives repeated damage from several active Radiation effects.
Removing Enemy Buffs
At Exclusive Weapon level 10, Atomic Blast can remove two combined stacks of buffs applied by enemy heroes. Eligible effects may include:
- Attribute increases.
- Counterattacks.
- Shields.
- Resistance effects.
- Attack-speed improvements.
- Damage bonuses.
The exact removal order and eligible effects should be checked in the current weapon description. The ability becomes more valuable against opponents whose formations depend heavily on temporary hero buffs.
Level 20 Missile Specialist
At level 20, Fiona’s weapon increases Attack, Defense, and HP by 7.5% for all Missile Vehicle heroes in the formation.
This is one of the weapon’s most important milestones because it strengthens the complete Missile squad instead of improving Fiona alone.
Is Fiona’s Exclusive Weapon Worth Upgrading?
The weapon is a strong long-term investment for accounts using Fiona in their main Missile formation. Even level 1 adds Radiation, while levels 10, 20, and 30 provide increasingly specialized benefits.
Prioritize it when:
- Fiona is already 5 stars.
- She is a permanent member of your main squad.
- You use a full or nearly complete Missile formation.
- Her normal skills and offensive gear are already developed.
- You can reach at least one important weapon milestone.
Delay it when:
- Fiona is used only in a secondary formation.
- Your frontline cannot keep her alive.
- Your normal skills and gear remain underdeveloped.
- Another main hero requires a more important Exclusive Weapon upgrade.
- You cannot reach a meaningful milestone beyond activation.
Important Note: Review the current Exclusive Weapon interface before investing. Shard requirements, release timing, skill effects, and numerical values may change through future updates.
Fiona’s Wall of Honor Bonus
After Fiona reaches 5 stars and the Missile Center reaches level 20, surplus Fiona shards can be invested through the Wall of Honor.
Her listed Wall of Honor milestone provides +0.50% Missile Hero Attack every 50 Honor levels. This allows additional Fiona shards to improve the Attack of eligible Missile heroes across the formation.
Review the Last War Wall of Honor guide before using hero-specific or universal shards on advanced Honor levels.
Is Fiona Worth Building?
Fiona is a strong investment for accounts committed to Missile Vehicle progression. Her full-team Tactic damage gives her a clear role, while her Season 5 Exclusive Weapon adds Radiation, buff removal, and a Missile squad bonus.
She is worth prioritizing when:
- You are building a dedicated Missile formation.
- You need a back-row hero who damages the entire enemy team.
- You can protect her with two durable frontline heroes.
- You plan to develop her Season 5 Exclusive Weapon.
- Your Missile Center and related research are already progressing.
She may deserve a lower priority when:
- Your main Tank or Aircraft squad remains incomplete.
- You do not have suitable frontline Missile heroes.
- Your Skill Medals and gear are already divided among too many damage dealers.
- You cannot reach her important star or weapon milestones.
- A stronger primary squad hero remains underdeveloped.
Fiona can still perform well outside a full Missile team, but her later Exclusive Weapon receives more value when several Missile heroes are used together.
Common Fiona Mistakes
- Placing Fiona on the frontline: Her damage depends on surviving through several skill cycles.
- Upgrading Ballistic Boost first: Atomic Blast and Double Trajectory normally provide greater early value.
- Treating Super Sensing as a normal skill: It is an Expertise effect with separate progression.
- Trying to activate Atomic Blast manually: Normal battles use automated skill activation.
- Assuming “anti-aircraft missile” creates another hidden bonus: Use the listed skill values and standard vehicle counter system.
- Ignoring defensive gear completely: Fiona produces no damage after being defeated.
- Spreading investment across too many Missile heroes: Complete a functional main squad before building several secondary heroes.
- Unlocking the Exclusive Weapon too early: Develop Fiona’s normal skills, stars, and gear first.
- Expecting Fiona to provide healing or protection: Her main contribution is Physical Damage.
Fiona and Account Progression
Building Fiona into a competitive Missile damage dealer requires Legendary Hero Shards, Skill Medals, strong gear, Missile Center upgrades, research, and Exclusive Weapon materials. Her best results also depend on a developed frontline and other Missile heroes.
