Only time I have seen this work is in underwater part of resistance. The rest of the time it does not come on at all for me.
Do you need a set DEX or level of acrobatics for it to work ?

It works. The buff just doesn't display properly anymore.

Shame the rest of the game seems to be broken - chat screen/crashes and memory leaks,
Whats gone wrong, have the DEVS all left or being fired ????
