Bethesda you may want to nerf the Falmer Shadowmasters because they are frikkin OP on master dificulty !!

Ive died like 10 times or more I had to use all my cooldowns just to [censored] kill it !

You chose to play on Master difficulty.
So you're the one making the game too hard for you and your character.

I agree they are very difficult in melee, but I usually find them quite easy to kill with stealth tactics.
There's always a way to kill an enemy, even on Master.

I have no problems with any other monsters but this falmer shadowmaster is frikkin hard
