I tried several times in dungeon rifts, underworld and Battlefield the ability "crumble" from my gunner voidlind and it never was able to steal fury or gain power, (while the heal seemed to work).
I did some experiment with Wicker Man Eddie, too and in this case I was able to steal fury once (in 6 "perfect" attempts).
Mine does it loads, maybe it's to do with level? My gunner voidling is 5*lev91
Maybe it's the level, Mine is 4*80.
Reading the description of the skill it should work every time (provided the enemy has some Fury, I suppose)
I did more experiments and it seems the amount of Fury stolen is little, probably not enough to gain one full point of Power.
The skill description is: -Reduce Fury of enemy team
-Gain Power based on the Fury taken
-Heal self based on missing HP
Ressurecting this one as Im wondering if its worth building the gunner voidling? If crumble doesnt add much power, or reduce fury, then it might not be worth it? I was kinda hoping that it would really help in the lol's in the dungeons....
I have a gunner voidling I've been messing with. The power move works, but it doesn't display the power/fury stolen until after the AI's turn (or death.)
Damage with the basic attack seems pretty low, but might get better with shards as it is 10% every level. Timing is really tough with this character, harder than the PSS in my opinion. The one plus I can think of is that this character is a power stealing machine with energy set equipped. It might get better with better talismans, but the yellow slot seems like a waste.
