the interval, or "decay power" has been set to both 0.10 and 100, neither of which makes any difference.
i set the initial damage to 10 once just to see if an initial damage of 0.00, like a stun time of 0.00, would be equal to infinite damage or something, resulting in the instant kill.
the ability does have a custom buff at the moment, but why would that affect anything? the buff is simply a little box that is on the unit and provides information. why would it matter?
it seems kinda obvious you probably know what the deal is eusira, what's the point of speaking in cryptic language that almost explains the problem but really only hints at it and says nothing definite.
