Determination or Grace better for endgame bosses?

I'm a bit confused about which one to use. Currently, I'm running these two auras for mapping and leveling but would like to switch one out for Malevolence to do endgame boss runs.

Some YouTubers suggest dropping Grace while I read here some players are in favour of dropping Determination.

Help!

If you are talking about your totem character keep determination, enables molten shell/VMS and you don't directly engage with enemies, plus it helps with phys spells.

You'd only keep grace if you had a good amount of armour anyway ~15-20k and several sources of reduced phys taken, endurance charges, phys taken as ele etc at which point grace becomes very good.

Thanks for clearing that up for me. :)

Id also add that grace is only good against attacks and most dangerous end game boss moves are spells.

I would only use grace over determination if you have a fair ES pool and use ghost dance(as grace would enable recovering the entire ES pool each hit most likely), otherwise stick with determination to enable things like molten shell.
