Ava is an A-rarity Blood Rose hero in Last Z who works as a hybrid hero with both damage and support value. She is not only useful because of her active skill damage, but also because she can increase Blood Rose faction attack through her exclusive talent.
This Last Z Ava guide covers her stats, skills, best use, upgrade priority, gear tips, formation advice, and mistakes to avoid so you can decide whether she is worth building for your account.

Is Ava Good in Last Z?
Ava is a good A-rarity hero for players building around Blood Rose. She is especially useful if you need a flexible hero who can add damage while also supporting Blood Rose heroes through her faction attack bonus.
Her biggest value comes from:
- Balanced hybrid stats
- Area damage from Perilous Potion
- Poison effect after upgrades
- Self ATK increase
- Blood Rose faction ATK bonus
- Solid role in early and mid-game formations
However, Ava should not usually take priority over stronger S-rarity heroes if you already have them. She is better used as a practical support-damage hero while you continue building your main long-term lineup.
Ava Skills in Last Z
Ava has four main skills. Her skill set gives her direct damage, normal attack scaling, self attack, and Blood Rose faction attack support.
| Skill | Type | Main Effect | Upgrade Value |
|---|---|---|---|
| Perilous Potion | Active Skill | Deals area damage with a 700 damage factor | Gains more damage and poison effect |
| Chemical Reaction | Normal Attack Boost | Increases normal attack damage to 450 | Improves normal attack damage factor |
| Attack Expert | Global Effect | Increases Ava’s self ATK by 900 | Adds more hero attack per star level |
| Faction Attack | Exclusive Talent | Increases Blood Rose hero ATK by 10% | Strong faction support value |
Perilous Potion

Perilous Potion is Ava’s active skill. She throws hazardous chemicals into a target area and deals massive damage to enemies with a 700 damage factor.
| Star Level | Upgrade Effect |
|---|---|
| 1 Star | Damage factor increases by 90 |
| 2 Stars | Damage factor increases by 90 |
| 3 Stars | Chance to cause additional poison damage |
| 4 Stars | Damage factor increases by 220 |
| 5 Stars | Poison effect is enhanced |
This is Ava’s most important combat skill because it gives her area damage and later adds poison. The poison effect makes her more useful in longer fights where extra damage over time can add up.
Practical Tip
Upgrade Perilous Potion first if Ava is part of your active march. It gives the most visible combat impact because it improves her burst damage and unlocks poison value at higher star levels.
Chemical Reaction

Chemical Reaction is Ava’s normal attack boost. It increases the damage of her normal attacks to 450.
| Star Level | Upgrade Effect |
|---|---|
| 1 Star | Damage factor increases by 45 |
| 2 Stars | Damage factor increases by 45 |
| 3 Stars | Damage factor increases by 45 |
| 4 Stars | Damage factor increases by 60 |
| 5 Stars | Damage factor increases by 105 |
This skill improves Ava’s consistent damage. It is not as flashy as her active skill, but it helps her stay useful outside of skill casts.
Practical Tip
Chemical Reaction is worth upgrading after Perilous Potion if you use Ava often. It helps her deal more stable damage across PvE and PvP battles.
Attack Expert

Attack Expert increases Ava’s self ATK by 900. It is listed as a global effect skill.
| Star Level | Upgrade Effect |
|---|---|
| 1 Star | Hero attack increases by 50 |
| 2 Stars | Hero attack increases by 50 |
| 3 Stars | Hero attack increases by 100 |
| 4 Stars | Hero attack increases by 200 |
| 5 Stars | Hero attack increases by 300 |
This skill improves Ava’s own damage output. Since she has a hybrid role, the extra attack helps her contribute more in combat instead of only acting as a faction support hero.
Practical Tip
Attack Expert is good, but it should not be your first priority unless Ava is one of your main damage heroes. For most players, her active skill and faction value matter more.
Faction Attack

Faction Attack is Ava’s exclusive talent. It increases the Hero ATK of the Blood Rose faction by 10%.
This is one of Ava’s most important reasons to use her in a Blood Rose lineup. Faction-based bonuses can make your full march stronger, especially when several heroes share the same faction.
Practical Tip
Ava becomes more valuable when you use her with other Blood Rose heroes. If your formation is mixed and does not rely on Blood Rose, her faction attack bonus loses a lot of value.
Best Ava Skill Priority
Ava’s skill priority depends on how much you use her. If she is only a temporary hero, do not spend too many rare resources on her. If she is part of your Blood Rose formation, focus on her damage and faction value.
| Priority | Skill | Why |
|---|---|---|
| 1 | Perilous Potion | Main active damage skill with poison upgrade value |
| 2 | Faction Attack | Boosts Blood Rose hero ATK |
| 3 | Chemical Reaction | Improves normal attack damage |
| 4 | Attack Expert | Adds self ATK but is less important than team value |
For most players, the best approach is to build Ava enough to support your Blood Rose team, then save premium resources for stronger long-term heroes.
Best Formation for Ava
Ava works best in a Blood Rose formation because her exclusive talent increases Blood Rose hero attack. Last Z faction bonuses also reward players for using multiple heroes from the same faction, with stronger bonuses when using 3, 4, or 5 heroes from one faction.
| Formation Style | Ava Value |
|---|---|
| Full Blood Rose team | Best use because she supports faction ATK |
| 3 Blood Rose + 2 other faction | Good option if you lack enough strong Blood Rose heroes |
| Random mixed team | Lower value because her faction bonus is less effective |
Blood Rose also works best with Assaulters, while Wings of Dawn works best with Shooters and Guard of Order works best with Riders.
Practical Tip
Use Ava with Blood Rose heroes first. If your strongest heroes are from another faction, Ava can still help early on, but she should not be forced into a formation where her faction bonus does not support your main lineup.
Best Gear for Ava
Because Ava is a hybrid hero, her gear choice depends on how you use her. If you use her mainly for damage, prioritize attack-focused gear. If you need her to survive longer, balance her with defensive gear.
| Gear Focus | Best For | Recommendation |
|---|---|---|
| Weapon / Gun | More damage | Best if Ava is used as a damage dealer |
| Helmet / Armor | More survival | Useful if Ava dies too quickly |
| Boots | Extra defensive value | Good for balanced hybrid use |
| Higher rarity gear | Long-term investment | Give only if Ava is part of your main formation |
General Last Z gear advice is to match gear with hero role. Attack-type heroes benefit more from gun equipment, while defense-type heroes benefit more from armor or boots.
Practical Tip
Do not give Ava your best gear if she is only a temporary hero. Save your strongest gear for S-rarity heroes or your main march carries.
Ava Upgrade Priority
Ava is worth upgrading if you are actively using Blood Rose heroes. She gives better value when her faction attack bonus supports multiple heroes in the same march.
| Upgrade Area | Priority | Notes |
|---|---|---|
| Level | Medium | Keep her close to your active formation level |
| Stars | Medium to High | Important for unlocking and improving skills |
| Perilous Potion | High | Main damage skill |
| Faction Attack | High | Strong Blood Rose support value |
| Gear | Medium | Upgrade only if she is used often |
| Universal Shards | Low to Medium | Save most premium shards for stronger heroes |
A good rule is to upgrade all important formation heroes to 4 stars first, because the 4th skill can be a major power boost. Going from 4 stars to 5 stars is usually less urgent than unlocking key skills across your whole march.
Best Use for Ava
Ava is best used as a Blood Rose support-damage hero. She is not a pure tank and not the strongest long-term carry, but she gives useful value when placed in the right team.
| Game Mode | Ava Performance |
|---|---|
| PvE fights | Good for area damage and poison |
| Creep fights | Useful if she is one of your stronger A-rarity heroes |
| PvP | Decent in Blood Rose teams, weaker outside faction synergy |
| Events | Good if combat events use your Blood Rose march |
| Main formation | Good early to mid-game, situational later |
| Backup formation | Solid option when stronger heroes are not available |
Practical Tip
Ava is best for players who are still developing their hero roster. Later, she may move into a secondary march when stronger S-rarity heroes become available.
Ava Strengths and Weaknesses
| Strengths | Weaknesses |
|---|---|
| Balanced Attack and Defense stats | Not as strong as top S-rarity heroes |
| Useful Blood Rose faction ATK bonus | Needs Blood Rose teammates for best value |
| Active skill has area damage | Poison value depends on upgrades |
| Can work in early and mid-game combat | May fall off in late-game main marches |
| Good hybrid role | Universal shards may be better saved |
Should You Invest in Ava?
You should invest in Ava if you are building a Blood Rose lineup or need a reliable A-rarity hero for early to mid-game progress. Her faction attack bonus makes her more valuable than a simple damage hero because she can improve the whole Blood Rose formation.
However, you should avoid overinvesting if you already have stronger S-rarity heroes. Ava is useful, but she is not usually the best place to spend your rarest upgrade resources.
Recommended Investment Level
| Player Type | Recommendation |
|---|---|
| Beginner | Build Ava if she is one of your best heroes |
| F2P player | Use her carefully and avoid wasting universal shards |
| Blood Rose player | Worth building for faction support |
| Heavy spender | Use until stronger premium heroes replace her |
| Late-game player | Better as a secondary or support option |
Mistakes to Avoid with Ava
- Do not build Ava outside Blood Rose without a reason. Her faction attack bonus is much stronger when used with Blood Rose heroes.
- Do not spend all universal shards on her too early. Save important resources for long-term heroes.
- Do not ignore Perilous Potion. This is her main combat skill and gives poison value at higher upgrades.
- Do not give her your best gear automatically. Prioritize your main carry heroes first.
- Do not judge her only by raw damage. Ava’s value also comes from faction support.
- Do not spread upgrades across too many heroes. Focus on one main formation first.
