I've tested and allocated it to an actual key. It's still not perfect but if you are in a lure and struggling you can use it to minimise damage whilst you heal a bit. (High HP recovery definitely helps)is it worth getting for warr
Surely you are referring to how the skill used to work? As of now it is definitely useful to regain some HP in a sticky situation.Just wait till you find it, its not a great skill and you wont use it much if ever. just buy a rev ring
