[Trigger] Heal over time with burst heal at end

[Majin[HELL]]

Okay, I'm making this ability that's akin to Lifebloom from World of Warcraft (if anyone knows what that is), basically it's a HoT which heals for an amount over time but when the duration of the spell ends it does a burst heal.
An advanced feature I'd like to add (if possible) as well is for the burst heal to be applied either when the spell ends or is dispelled.

So far I based the spell off of Rejuvination (obviously) and I'm trying to trigger the final burst heal effect.

Here's what I have so far (it looks a bit retarded, I know lol):
