This little Delve Boss is sometimes way to difficult

You know the little Delve Boss for the fossil? When he has buffs like movement speed and attack speed you can deinstall the game.

He does way too much physical damage. I would appreciate when he does a bit less.

I remember with a champion i had a similar problem and i had huge damage reduction.
