To reach 1 billion damage against the Osh boss on auto-mode in Hero Wars: Alliance Adventure: Alliance Adventure, build your team around the core trio of Isaac, Nebula, and Judge. This composition automates high physical damage output while preserving enough defensive support to survive long boss fights without manual ability timing.
Core Trio Roles and Positioning
The setup relies on specific skill interactions between three main heroes:
| Hero | Role | Key Function |
|---|---|---|
| Isaac | Primary Damage Engine | Ramps up damage over long boss encounters. |
| Nebula | Force Multiplier | Buffs the physical attack of adjacent allies to scale total damage output. |
| Judge | Shield and Utility Support | Mitigates heavy boss attacks to maintain team survivability. |
Place Nebula directly adjacent to your primary damage dealers. Her stat amplification targets neighboring heroes, so optimal placement maximizes buff uptime on Isaac and your additional offensive picks.
Filling the Remaining Team Slots
After locking in Isaac, Nebula, and Judge, fill the final two roster spots based on your current team performance:
- Offensive Fillers: Select heroes that grant additional physical attack buffs to help Isaac reach the score target faster.
- Defensive Fillers: Select heroes that provide party-wide defensive stats or shields if your lineup dies before the boss timer ends.
Auto-Mode Execution and Tuning
This lineup works on auto-mode because ability triggers naturally align with Osh's attack patterns, removing human timing errors. However, success depends on meeting minimum power and investment thresholds for your target boss tier.
If your auto-mode runs fall short of the 1 billion score, adjust your stat priorities:
- If the team dies early: Upgrade Judge's defensive stats and defensive artifacts to stabilize survivability.
- If the team survives but damage is low: Shift upgrades to Isaac and Nebula's offensive stats to boost physical attack scaling.
