So, this is an interesting effect. Click, cast time 1.5s, recast 10s, deals 500 dmg and heals you.
I'm not sure this is intentional (normally Kiss of Life is just a combat proc), but if it is, the range is 255. (one of the farthest ranged DD's in game if i'm not corrected).

So, just wanted to point this out... I don't mind.. just more curious.
