[Spell] birthmark

I need help creating a passive spell that should goes like this

If this units health goes down below 15% it will automatically gain 350 health regen per second. Cannot be used more than 15 times. Replenishes only when unit kills 25 units.


I already figures how to trigger the effect at below 15% health and i already have the spell that would kick in the health reg..... My problem is creating the 15 time limit and the replenishment after the 25 unit kill..

any help is dearly appreciated

Replenishes only when unit kills 25 units.

You mean that the 350 HP Regen will be removed once the unit has killed 25 units in that period ?

Okay, after 15 times, the spell does nothing when the unit reaches health 15% or below ?

no after 15 times that the 350 health regen has been activated the spell would then do nothing up until the unit has killed 25 units then it can now receive again the 350 health regen
