This is the thing that happens in boss fights does say "Proelium Fatale" that means it's hard boss fight. But in the game if you have experience or higher level sinner than the boss it's too easy. I will give you how Limbus Company works: Limbus Company is a turn-based gacha RPG where you control a group of 12 characters called Sinners, each with different versions called Identities that define their stats and skills. In battle, your Sinners draw random skills each turn, and these skills use a coin-flip system where heads give stronger effects and tails weaker ones. When your skill meets an enemy’s, they enter a Clash, and the higher roll wins—winning cancels the enemy’s action, while losing means you take damage. Enemies also have resistances and weaknesses to different attack types, so using the right skills at the right time is key. Battles flow by selecting which skills target which enemies, watching them automatically resolve, and managing resources to unleash powerful E.G.O.
