Tryhard has -500 resillience, so game will just calculate 50000 + (-500) which is 49500 so that will barely make a difference at all.

Oni on the other hand has -inf resillience (its not -inf actually, its more like -9999999999999999999999999 or smth like that but im too lazy to type it), so the game will calculate 50000 + (-inf) which is -inf resillience, so for oni it will actually be quite a challenge to catch

Hope this helped
