Best Free Heroes to Invest in for Last Asylum Plague
The top pick for most players is Doc – his AoE heal and cleanse keep your squad alive through the Plague’s relentless chip damage, and he’s obtainable early via story mode. He scales well into late game because his heal scales with his own max HP, making him a durable investment that never falls off.
What to Look For
When deciding which free heroes to invest in, focus on these criteria:
- Utility over raw damage – Sustained fights against the Plague require healing, cleansing, and debuffs more than burst DPS.
- Early availability – You want heroes you can star-up and gear from the start, not ones locked behind late-game stages.
- Faction synergy – Matching heroes from the same faction (e.g., Wanderers, Scavengers) gives bonus stats and energy, so pick a core faction early.
- Scaling – Check if a hero’s abilities scale with stats you can boost (HP, ATK) rather than flat values that become irrelevant.
- Versatility – Heroes that work in PvE, PvP, and boss fights save resources.
Doc
Strengths: Doc is the best free healer. His active skill heals all allies for a percentage of his max HP and removes one debuff (including Plague stacks). His passive increases healing received by the whole team, and his basic attack has a chance to stun.
Trade-offs: He deals negligible damage and is squishy if not geared. He also needs high star levels to keep up with incoming damage.
Best for: Every player, but especially those who want a reliable healer for boss fights and long stages. If you only invest in one hero, make it Doc.
Brawler
Strengths: Brawler is a front-line tank with high HP and a taunt that forces enemies to attack him. His passive grants damage reduction when his HP drops below 50%, and his active deals AoE damage and applies a 2-turn defense down.
Trade-offs: His damage is mediocre, and he needs high investment to survive burst damage. He also lacks self-healing, so he depends on Doc or lifesteal.
Best for: Players who need a solid tank to protect squishy DPS. He pairs well with Doc to keep him alive.
Sharpshooter
Strengths: Sharpshooter is a single-target DPS with high crit rate and crit damage. His active skill deals massive damage to the enemy with the lowest HP, executing low-health targets. His passive increases his crit rate against debuffed enemies.
Trade-offs: He has no AoE, so he’s slow in wave-clearing. He’s also fragile and needs protection.
Best for: Players who want to focus down bosses or high-priority targets. He shines when paired with heroes that apply debuffs, like Doc’s stun.
Medic
Strengths: Medic is a secondary healer with a single-target burst heal and a cleanse. Her passive gives the whole team a shield at the start of battle, which helps absorb the Plague’s opening burst. She also has a revive passive with a 2-turn cooldown.
Trade-offs: Her heal is single-target, so she can’t keep up with AoE damage. Her shield is small and scales with her ATK, which is low.
Best for: Players who want a second healer for tough stages or PvP defense. She’s also useful when Doc is banned or unavailable.
Engineer
Strengths: Engineer is a support hero that places turrets that deal damage and slow enemies. His passive increases the whole team’s energy recovery, letting you use ultimates faster. His active skill deploys a turret that taunts enemies.
Trade-offs: The turret has low HP and can be destroyed quickly. His damage is low, and he needs to stay alive to keep the energy buff.
Best for: Players who want to accelerate their team’s ultimate rotation. He’s especially good in PvP where energy management matters.
Hound
Strengths: Hound is a summoner that calls a dog to fight alongside him. The dog has high HP and taunts, acting as an extra tank. Hound’s passive increases the team’s crit damage, and his active buffs the dog’s attack.
Trade-offs: The dog can be killed, leaving Hound vulnerable. Hound’s own damage is low, and he needs to survive to keep the buff.
Best for: Players who want a second tank or a pet-focused team. He’s fun to use and provides good utility.
How to Choose
Your choice depends on your budget and playstyle. If you’re a free-to-play player with limited resources, focus on one hero from each role: a tank (Brawler), a healer (Doc), and a DPS (Sharpshooter). This gives you a balanced team that can handle most content. If you’re willing to spend a little, you can invest in Medic or Engineer for more utility.
Common trade-offs: investing in a DPS like Sharpshooter makes farming faster but leaves your team fragile. Investing in a tank like Brawler makes you tanky but slows down battles. A healer like Doc is essential but doesn’t contribute to damage.
For PvP, prioritize heroes with crowd control (Engineer, Doc) and high burst (Sharpshooter). For PvE, prioritize sustain (Doc, Brawler) and AoE (Brawler’s active).
Frequently Asked Questions
Can I get these heroes for free?
Yes, all of these heroes are obtainable through story mode, daily rewards, and free summons. They are not paywall-locked.
How many stars should I invest in them?
At least 5 stars for main team members. 6 stars for your core (Doc, Brawler) if you can afford it. Stars increase base stats and unlock passives.
What gear should I put on Doc?
Prioritize HP% and Energy Regen. Doc’s heal scales with max HP, so stack HP. Energy Regen lets him ult more often.
Are there any other free heroes worth mentioning?
Yes, but they are niche. For example, the Sniper is a long-range DPS with high crit, but she’s fragile. The Juggernaut is a tank with self-shield, but he lacks taunt. These are situational.
Should I focus on one faction?
Yes, faction bonuses are significant. Pick a faction that includes your core heroes (e.g., Wanderers have Doc and Brawler) and build around them.
What’s the best team composition for the Plague?
A typical team is Brawler (tank), Doc (healer), Sharpshooter (DPS), and Engineer (support). This gives you sustain, damage, and energy control.
Bottom Line
Doc is the single best free investment because he’s essential for every game mode and never falls off. Pair him with Brawler for tanking and Sharpshooter for damage, and you have a solid core that can carry you through the Plague. Start with Doc, then Brawler, then Sharpshooter, and you’ll have a team that works for both PvE and PvP.
