[RM2K3] AUTO-LIFE ABILITIES...WITH ENEMIES

So, I'm sitting here trying to update my enemies/bosses finally, and I'm working on the fairy types, as you may have noticed from my other topic. The fairies in my game all have innate Auto-Life, where after being dead for X turns (I'm going to set this to 30 turns for right now to see if that's too little or too much), they'll revive with 50% Max HP. I'm sitting here trying to wrap my head around doing this (I have in my Turns Elapsed x1 common event a line that calls a common event that'll reduce the timers on abilities and the like by 1 every turn. I have a line of code in there for enemies 1-8 to tick down 1 number every turn taken during battles). However...I'm drawing a blank on how to actually SET UP the auto-ability. If I set it to its own page for each enemy, not only will that probably take up useful space (I MIGHT be able to spare it though), but I feel like it'll loop in on itself and constantly reset the starting value to 30. If I set it to 30 in the Turns Elapsed x1 event, I feel it'll do the same.

So...can anyone help me out with this bit? I feel it should be super simple and whatnot. Screenshots of what I'm talking about:



1) As shown here, common event is called each and every turn to tick down all timers by 1.




2) Said common event has all of the timers, including the auto-life timer for Fairy enemies (or any enemy really, if I wanted them to have Auto-Life), which is where they will tick down by 1 every turn.


3) Setting up the event where it won't loop in on itself is the tricky part.
