Error I'm getting with fury, causes nothing to show up as suggestion other than execute when i have the fury for it.

Here's my gear

Fixed by unequipping t19.

Another issue is no suggestions showing when im hitting a dummy and its on very low hp, but that's not something you'd come across very often in the real game.

Another question,

Could Ring of Collapsing Features get added as on-use item?

For items, we don't really support them
