Fiona Last War Survival: Skills, Tips & Hero Guide

Fiona is a UR Missile Vehicle damage dealer in Last War: Survival who specializes in Physical Damage and attacking the full enemy formation. Her most important normal skill is Atomic Blast, while her Season 5 Exclusive Weapon adds Radiation damage, enemy-buff removal, and a powerful full-Missile team bonus.

For Skill Medals, a practical Fiona priority is Atomic Blast first, Double Trajectory second, and Ballistic Boost third. Super Sensing belongs to separate Expertise progression. Fiona should normally stay in the back row behind durable heroes so she can survive through multiple Tactic cycles.

Fiona Hero Overview

Fiona, also known as the Lion Cub, is built around sustained Physical Damage and multi-target pressure rather than frontline survival.

• Rarity: UR
• Vehicle Type: Missile Vehicle
• Specialty: Damage Dealer
• Damage Type: Physical Damage
• Listed March Size: 350
• Main Role: Full-team Tactic damage and sustained Missile offense
• Best Position: Back row

Her base kit revolves around Atomic Blast hitting every enemy, Double Trajectory supplying regular Physical Damage, and Ballistic Boost increasing Fiona’s Physical Damage throughout the fight.

Fiona also benefits from upgrades to the Missile Center, which improves statistics for eligible Missile Vehicle heroes.

How to Get Fiona in Last War

Fiona is not one of the earliest heroes available from the standard Tavern pool. Her acquisition options expand as a warzone progresses.

Depending on your server age and season, Fiona can appear through:

• Her original limited or paid hero release.
• Ghost Ops after the feature becomes available, which can provide shards for heroes not yet in the normal Tavern pool.
• Later seasonal recruitment and Legend Returns availability.
• The regular Tavern after Fiona is added to the eligible pool on sufficiently progressed warzones.
• Hero Choice Chests or other season-dependent reward systems when Fiona is included.

Because these unlocks are tied to warzone progression, do not spend recruitment resources based only on another server’s timeline. Open the current Tavern, event, or choice-chest information and confirm that Fiona is actually listed before spending tickets or premium currency.

Fiona Skill Priority

If you are deciding where to spend Fiona’s Skill Medals, use this order as the default:

Priority	Skill	Why It Matters
1	Atomic Blast	Hits the entire enemy formation and defines Fiona’s main damage role.
2	Double Trajectory	Provides frequent Physical Damage between Tactic casts and gains extra importance after her Exclusive Weapon is activated.
3	Ballistic Boost	Raises Fiona’s Physical Damage throughout battle but does not create a separate attack.
Separate	Super Sensing	Expertise progression rather than a normal Skill Medal target.

Do not interpret this as a requirement to completely max Atomic Blast before touching anything else. Early skill levels are relatively inexpensive, so keeping all three normal skills functional is reasonable.

As costs rise, direct the largest share of Skill Medals toward Atomic Blast, keep Double Trajectory reasonably close, and add Ballistic Boost levels when they offer good value without delaying the other two.

For broader resource planning, see the Last War hero skill upgrade priority guide.

Fiona’s Skills Explained

Double Trajectory

Double Trajectory is Fiona’s auto attack. Its documented effect deals Physical Damage equal to 408.11% of Fiona’s Attack.

• Type: Auto Attack
• Cooldown: 1.35 seconds
• Damage Type: Physical Damage
• Role: Consistent damage between Atomic Blast casts

Star progression increases its additional damage. The listed milestones progress from +30% additional damage through higher bonuses, reaching 270% at the final listed star effect.

The wording of the skill references an anti-aircraft missile, but you should not assume that this creates an undocumented second Aircraft-specific multiplier. Fiona already participates in the normal Missile-versus-Aircraft vehicle counter system.

Ballistic Boost

Ballistic Boost is Fiona’s passive damage skill. Its documented base effect increases her Physical Damage by 30% during battle.

• Type: Passive
• Cooldown: None
• Role: Improves Fiona’s overall Physical Damage

Each listed star effect adds another three percentage points to the skill’s effect. Because Ballistic Boost benefits Fiona throughout battle, it should not be ignored simply because it sits third in the normal Skill Medal order.

When the next Atomic Blast or Double Trajectory upgrade becomes expensive, a cheaper Ballistic Boost level can be an efficient way to keep Fiona progressing.

Atomic Blast

Atomic Blast is Fiona’s defining Tactic skill. It attacks all enemies, with each rocket dealing documented Physical Damage equal to 718.17% of Fiona’s Attack.

• Type: Tactics
• Cooldown: 10 seconds
• Damage Type: Physical Damage
• Role: Full-formation burst damage

Its star effects follow the same listed additional-damage progression as Double Trajectory, eventually reaching a 270% additional-damage effect at the final milestone.

Atomic Blast is the strongest reason to prioritize Fiona’s Skill Medals because one cast can pressure every surviving enemy hero rather than a single target.

Normal combat controls Tactic activation automatically, so you do not manually save Atomic Blast for a particular moment. Instead, positioning and survivability matter because keeping Fiona alive gives her more opportunities to cast it.

Super Sensing

Super Sensing is Fiona’s Expertise effect. Its documented bonuses are:

• HP +20%
• Attack +20%
• Defense +20%
• Skill Cooldown Rate +10%

The Attack increase directly supports her damage, while HP and Defense help a fragile back-row hero survive. The cooldown bonus also complements her damage cycle.

Do not include Super Sensing as a fourth Skill Medal priority. Expertise uses its own progression system.

Best Position for Fiona

Fiona should normally be placed in the back row. Her value comes from remaining alive long enough to use repeated auto attacks and Atomic Blast casts.

A typical structure is:

• Front row: Two durable heroes capable of absorbing incoming attacks.
• Back row: Fiona, another damage dealer, and a third attacker or utility hero.

If Fiona is repeatedly dying before her next Atomic Blast, check the frontline and her defensive gear before simply adding more Attack. An attacker who survives for another full skill cycle can outperform one with slightly better offensive statistics who dies early.

Best Missile Team for Fiona

A natural dedicated Missile formation uses Fiona alongside Tesla, Swift, Adam, and McGregor.

Position	Hero	Main Job
Front Row	Adam	Defensive frontline presence
Front Row	McGregor	Second frontline body and pressure
Back Row	Tesla	Energy-damage carry
Back Row	Fiona	Physical multi-target damage
Back Row	Swift	Additional Missile damage and finishing pressure

Tesla and Fiona complement each other particularly well because they provide different damage types. Tesla contributes Energy Damage while Fiona contributes Physical Damage, forcing opponents to account for both.

Do not force a five-Missile formation before the heroes are developed enough to function. Two highly upgraded off-type frontline heroes can be more useful during progression than replacing them immediately with low-star Missile alternatives.

Fiona for F2P and Developing Accounts

Fiona can be obtained without relying exclusively on her original paid release once a warzone reaches later acquisition systems, but that does not make a full Missile squad cheap to build.

If Fiona is not part of your main formation yet:

• Keep your strongest established squad functional first.
• Collect Fiona shards when efficient opportunities appear.
• Avoid spreading Universal Legendary Hero Shards across five unfinished Missile heroes simultaneously.
• Build a usable frontline before heavily investing in Fiona’s late-game weapon.

Fiona Matchups: Missile vs Aircraft and Tanks

The Last War vehicle counter triangle matters most in competitive battles:

• Missile Vehicles counter Aircraft.
• Tanks counter Missile Vehicles.
• Aircraft counter Tanks.

This makes Fiona particularly relevant when your opponent relies on an Aircraft formation. Against a similarly developed Tank squad, the vehicle matchup works against her Missile team.

Type advantage does not replace progression. Hero stars, Skill Medals, gear, research, troops, Drone development, decorations, Tactics Cards, and Exclusive Weapons can still decide fights where one side is significantly stronger.

Best Gear for Fiona

Fiona is an attacker, so her gear strategy should favor damage while maintaining enough survivability to stay active.

1. Gun: First offensive priority because Attack directly supports Fiona’s Physical Damage and later Radiation.
2. Data Chip: Strong secondary offensive investment for a damage dealer.
3. Radar: Move this higher when Fiona is dying too quickly to skill-heavy or Energy Damage opponents.
4. Armor: Useful durability, but usually behind her main offensive pieces.

Your account-wide gear order matters more than Fiona’s isolated build. If Tesla is your primary Missile carry or your frontline is collapsing immediately, those heroes may deserve the next premium gear upgrade before Fiona.

Use the Last War gear upgrade and promotion guide before spending large quantities of Upgrade Ore, Dielectric Ceramic, or Blueprints.

Fiona Exclusive Weapon

Fiona’s Exclusive Weapon arrives in Week 1 of Season 5. To activate it, Fiona must be 5 stars and you need 50 Fiona-specific Exclusive Weapon Shards.

After activation, Universal Exclusive Weapon Shards can be used for further levels. The weapon progresses up to level 30 and also improves Fiona’s core statistics while increasing the maximum level of her skills.

Weapon Level	Major Effect	Why It Matters
1	Double Trajectory applies 1 Radiation stack	Immediately introduces Fiona’s damage-over-time mechanic
10	Atomic Blast dispels a combined total of 2 hero-applied buff stacks	Adds useful PvP utility against buff-dependent formations
20	All Missile Vehicle heroes gain 7.5% Attack, Defense, and HP	Major full-squad breakpoint for committed Missile players
30	DoT stacks let Fiona’s Tactic dispel additional buff stacks, up to 5	Expensive late-game utility for a developed formation

How Fiona’s Radiation Works

Radiation deals Physical Damage equal to 5% of Fiona’s Attack every second for 20 seconds.

The maximum Radiation stacks an enemy can hold equals the number of Missile Vehicle heroes in Fiona’s squad multiplied by two, up to a maximum of ten stacks.

This creates a direct synergy with a full five-Missile lineup. More Missile heroes raise Fiona’s possible Radiation stack ceiling, giving her Exclusive Weapon more long-term value in the formation it was designed to support.

Exclusive Weapon Level 10: Buff Removal

At level 10, Atomic Blast gains the ability to dispel a combined total of two stacks of buffs applied by enemy heroes.

The documented eligible categories include effects such as attribute boosts, counterattacks, shields, and resistance-related buffs. This gives Fiona utility beyond raw damage against formations that rely heavily on temporary hero effects.

Exclusive Weapon Level 20: Missile Specialist

Level 20 is one of Fiona’s strongest long-term breakpoints because Missile Specialist increases Attack, Defense, and HP by 7.5% for all your Missile Vehicle heroes in battle.

Instead of upgrading Fiona alone, the investment now strengthens the entire dedicated Missile formation.

Is Fiona Worth Building?

Fiona is a strong long-term project for players committed to Missile Vehicle progression. Her base kit already offers full-team Physical Damage, while her Exclusive Weapon adds mechanics that become increasingly valuable in a dedicated Missile formation.

Prioritize Fiona When:

• Missile is your main or planned competitive formation.
• You already have enough frontline durability to protect her.
• You need Physical Damage alongside Tesla’s Energy Damage.
• You expect to reach Fiona’s 5-star and Exclusive Weapon milestones.
• You frequently face Aircraft formations in PvP.

Delay Heavy Fiona Investment When:

• Your first main squad is still incomplete.
• Your frontline dies before your back-row heroes can perform.
• You are splitting Skill Medals and Universal Shards across too many unfinished heroes.
• You do not plan to develop a Missile squad for a long time.
• A more important carry or Defender is still missing a major breakpoint.

If you would rather begin with more developed progression instead of building every Missile hero from scratch, comparing an established Last War account for sale is an optional alternative. Check the actual Fiona stars, Exclusive Weapon level, Missile teammates, gear, and other listing details before deciding whether an account fits your goals.

Fiona Wall of Honor Bonus

Once Fiona reaches 5 stars and the Missile Center meets the Wall of Honor requirements, surplus Fiona shards can continue contributing to Missile progression.

Fiona’s documented Wall of Honor milestone gives +0.50% Missile Hero Attack every 50 Honor levels, making her one of the offensive Wall of Honor options for a Missile-focused account.

Review the Last War Wall of Honor guide before committing Universal Legendary Hero Shards to advanced Honor progression.

Common Fiona Build Mistakes

• Putting Fiona on the frontline: She is a damage dealer who benefits from surviving multiple skill cycles.
• Upgrading every skill equally: Atomic Blast should normally receive the largest share of Skill Medals.
• Treating Super Sensing as a normal skill: It belongs to Expertise progression.
• Ignoring survivability: More Attack is wasted if Fiona dies before another Atomic Blast.
• Overbuilding defensive gear: Fiona should not consume every premium defensive resource just to compensate for an underdeveloped frontline.
• Forcing five Missile heroes too early: A stronger mixed formation may outperform an unfinished mono-Missile squad.
• Assuming Fiona is permanently paid-only: Later progression adds additional acquisition routes.
• Rushing Exclusive Weapon level 30: Levels 1, 10, and 20 already provide important breakpoints.
• Ignoring the vehicle counter: Missile teams are naturally better into Aircraft and disadvantaged into Tanks.

FAQs

What is the best Fiona skill priority in Last War?

Prioritize Atomic Blast first, Double Trajectory second, and Ballistic Boost third. Super Sensing uses separate Expertise progression rather than the normal Skill Medal path.

How do you get Fiona in Last War?

Fiona first appears through limited availability, while later warzone progression opens additional routes such as Ghost Ops and seasonal Tavern or Legend Returns recruitment. Her exact availability depends on your server’s progression, so check the current recruitment pool before spending resources.

Where should Fiona be positioned?

Fiona should normally be placed in the back row behind two durable frontline heroes. Her role is to survive long enough to use Atomic Blast repeatedly rather than absorb direct attacks.

What is the best Missile team for Fiona?

A natural full-Missile core uses Adam and McGregor in front with Tesla, Fiona, and Swift in the back. During progression, stronger off-type heroes may still outperform low-star Missile replacements.

When does Fiona get her Exclusive Weapon?

Fiona’s Exclusive Weapon becomes available during Week 1 of Season 5. Fiona must be 5 stars, and activation requires 50 Fiona-specific Exclusive Weapon Shards.

Conclusion

Fiona is a back-row Missile damage dealer whose strength comes from full-team Physical Damage and strong late-game scaling. Prioritize Atomic Blast, follow with Double Trajectory and Ballistic Boost, and protect her behind a reliable frontline.

Her Season 5 Exclusive Weapon is the biggest long-term upgrade, adding Radiation at activation, buff removal at level 10, and a 7.5% Attack, Defense, and HP bonus for all Missile heroes at level 20. For more builds, season updates, and progression guides, visit the Heaven Guardian Last War guides.
