Question Creating an Armor that heals for a small percentage after you kill a mob

Looking for ideas on how to accomplish this without having to change around code or cause any exploitation.

I have something similar on a wieldable item that randomly does a heal proc so it would be something based off that.
Any help would be great!

I think the problem will be in knowing when the player has killed a mob. You can see when the player is fighting and not fighting but there are variables between such as fleeing. If you use the mob-death-message, it could be a different player with a different mob death.

Another thing to think about would be the intensity of the heal. For instance: would you heal the same amount for a one-hit fido as for that dragon that took you an hour and used up all your heals?

The trigger you've used just heals as you are fighting which is relatively easy. It might be more fun (triggerly speaking) to upgrade the healing according to how long you've been fighting as opposed to randomly but checking to see IF you're fighting is much easier than:
Are you fighting now?
Were you fighting a second ago?
If you were fighting a second ago but not now, how did the fight end?

I suppose you might be able to have it depend on the experience gained from a won fight but I don't know how that could be triggered. If you could figure that out, then the intensity of the heal could be based on the experience gain, although this doesn't always reflect the difficulty of the fight. That one-hit fido probably didn't generate any experience so there would be no healing.

I think this may be a use case for a new type of trigger (OBJECT_DEATH_TRIGGER?)

That's an interesting thought. Darn! I was thinking that a mob death trigger would work but that would mean putting a trigger on every mob or only having the armor work with certain mobs.

Hmm, how about a mob death trigger that the armor attaches?
Is the player fighting?
Who is the player fighting? Is it a mob?
Attach a death trigger to the mob.
If the trigger fires, then the mob has died so check to see if the killer is the owner of the armor that attached the trigger.

It's kinda weird but it has possibities. Maybe?

I wrote a trigger years ago that does damage on hit.

tstat 38215 maybe will be of some help.
I actually have alot of wierd crap in 382 zone, free free to browse.
