Boss invulnerability and 1 shots...

Feels terrible. You cant damage the boss but it can 1 tap me through 8k energy sheild and full resistances. The idea is to prevent people from spawn camping the boss, but it still incentives the exact same playstle, just after waiting a few seconds. Meanwhile melee players just get shafted as per usual. Not being able to interact with the game is not something you should be striving to add more of. Theres already enough silly undamageable dialog phases during boss fights, it breaks imersion and feels terrible.

If you want an actual solution to the problem, just make it so that only actions that are taken after the boss fully spawns in can interact with that bosses hitbox.
