Hello everyone,
At the moment i have to click on it every 30 Seconds during ini runs. And when i have to cancel (heal is Frozen,etc...)the buff have a CD.
My suggestion is to change Blood arrow that i can activate it when i want and cancel it when i want without a running time or cd.

This would change the buff mechanic back to as it was waaaaaaayyyy back in the day, I really like that.
Maybe if that would make the buff stronger than intended in some way, a (10sec) cooldown could be added after the buff is removed, same as it is with Shadow Explosion or Self-Distortion, so players can't rebuff it instantly again.
Cheers!
We have plans for this skill which will be applied along with class balance patch soon.
Greetings.
