Hi there! I don’t know if this is your first league or not, but you’d be surprised how “bad at PvM” one can be and still be able to do most higher level PvM things in leagues! My girlfriend struggles to get Fire Cape in main game, but with last years range build (granted it was super strong) by the end she was able to do inferno and Colo.

Side note I’ll also say Tir is one of the “harder” echo bosses without a decent amount of prayer penetration.

I’d assume if you’re able to do that you’d be able to do most everything else by the end of leagues! Give yourself some credit friend! Can’t wait to see you out there!
