Hero Upgrade Guide

In Last Asylum, your hero strength heavily affects both PvE and PvP performance. Hero Might is determined by four main factors:

  • Hero Level
  • Star Rating
  • Skill Level
  • Gear (Equipment)

Improving these areas will significantly increase your hero’s combat effectiveness.

1. Hero Level

Heroes of different rarities — Orange, Purple, and Blue — have different base Might values.

  • Orange heroes are the rarest and have the highest base stats and Might.
  • Hero levels are upgraded using Antitoxin, the primary resource for leveling heroes.
  • As hero levels increase, the Antitoxin cost also increases.
  • Your hero level cap depends on your Sanctuary level. Upgrading the Sanctuary raises the maximum hero level.

Benefits of Leveling Heroes

Increasing hero level improves:

  • ATK
  • DEF
  • HP
  • Overall Hero Might
  • Skill effectiveness
  • Gear bonuses

Higher-level heroes gain stronger scaling from both skills and equipment.

2. Star Rating

A hero’s Star Rating also contributes heavily to their individual Might.

Increasing star levels:

  • Unlocks stronger skill effects
  • Enhances active skill damage
  • Improves passive skill bonuses
  • Raises the maximum skill level cap

Why Star Upgrades Matter

Star upgrades are one of the best long-term investments because they improve both base stats and skill scaling simultaneously.

3. Hero Skills

Hero skill upgrades provide one of the largest boosts to overall Hero Might.

Skills are upgraded using:

  • Medals

Benefits of Skill Upgrades

Upgrading skills increases:

  • Skill damage
  • Buff effectiveness
  • Passive bonuses
  • Utility effects

Because skills directly affect battle performance, prioritizing core hero skills can greatly improve combat efficiency.

4. Hero Gear (Equipment)

Each hero can equip four gear types:

Gear TypeMain Bonuses
SwordATK, ATK%, DEF, Crit%
ArmorDEF, DEF%, HP, HP%, Physical Damage Resistance
GauntletsATK, HP, ATK%, All Damage Resistance
BootsDEF, DEF%, HP, HP%, Energy Damage Resistance

Gear Priorities by Hero Class

Defensive Heroes

Focus primarily on:

  • Armor
  • Boots

These provide survivability through DEF, HP, and resistance stats.

Offensive Heroes

Focus primarily on:

  • Sword
  • Gauntlets

These maximize ATK, Crit%, and offensive scaling.

Important Hero Upgrade Tip

When upgrading heroes in Last Asylum, avoid spreading your resources across too many characters.

Resources such as:

  • Antitoxin
  • Medals
  • Star upgrade materials
  • Equipment materials

become increasingly expensive and difficult to obtain at higher levels. Because of this, you should focus your investments only on heroes that you truly plan to use in battles.

Smart Upgrade Strategy

Before investing resources:

  • Decide on your main battle lineup
  • Prioritize your strongest or highest-rarity heroes
  • Consider each hero’s role (Attack, Defense, Support, etc.)
  • Plan for both PvE and PvP usefulness

Why This Matters

Upgrading unused heroes can:

  • Slow your overall progression
  • Waste valuable materials
  • Delay power spikes for your main team

A well-planned hero upgrade path allows you to build a stronger, more efficient team and maximize your overall Hero Might much faster.
