Well It is not gona be a pretty sight:
EDIT: Damn sorry to have bothered you with this one, after correcting the wrong buff error I mentioned below the thing works as it should. I assumed that it put the buff on itself since it showed a distance ring around itself when you hover the curser over the ability. Again sorry.
Note: while taking screenshots I noticed the cluster warhead ability which is the same, just done for a period instead of the whole time (first noticed now cause I haven't played mutch). Some differences I noticed is that the first buff have PrioritizeOldBuffs by me while the cluster have PrioritizeNewBuffs an other thing I noticed is that the 2nd buff (spawn damage) have an error in the buff leading to a wrong buff (it excists, but have a fixedLevel0) so It might apply the radius effect on the target, but I dont apply damage. Also the different finishconditions are quite new for me, so they might be wrong.
