The three easiest was the one where they regen health
All you to do is barefist
Other one is kill all the enemies before time runs out
Lastly don’t get hit ....when the Stone Mountain brute pops up just hit l2 when he opens chest to throw a big ass rock in rage mode
I did the impossible trials 3 times to fully level up
I could never beat the one where y it adds time to after every kill because of the revenant and elf boss til recently
I did it for fun after I beat queen Sigrun I used the same talisman of unbound potential
