-Every boss in the game is harder than Margit. The third boss is harder than Malenia so it only scales up from there

-There are no crutch builds that will let you cheese or one-shot these bosses. They can only be beaten by properly learning the fight

-Uses a guard system like Lies of P where you have no chance against the boss unless you routinely "perfect guard" the attacks by pressing block at the split second they connect

-NPC summons are weak and ineffective and you can't summon other players. Nobody can kill these bosses for Doodikoff

-Doodikoff can't overlevel either, because your skill points are capped based on what bosses you've beaten
