Boss-Specific Strategies

1. Swamp Walker
- Time to Kill: 12 seconds
- Swamp Walker's high HP may trigger a second phase if he enrages, but he can usually be defeated in one phase.

2. Pyromaniac
- Time to Kill: 10 seconds
- Pyromaniac has low HP and easy mechanics, making him a breeze for Ultimate Lepic.

3. Devour, Executioner, Dead Bride
- These bosses go down quickly with little resistance, especially Devour.

In group fights like Obstructor and Frost Walker, Ultimate Lepic remains effective.
