"Might" was code for "definitely", Paul.
Okay, after looking over the SAs, i -definitely- know I'm doing it wrong. Unfortunately I don't know what I'm exactly doing here. So...assuming the characterRegeneration SA is right (I just modified the Troll one, and by modifying, i mean changing a word or two), this is the one I used on the item itself:
name = item_SymbiotecharacterRegeneration
[OnReady] = $SET_CHARACTER_SA($CharacterContext(),"characterRegeneration","3");
[OnUnReady] = $DELETE_CHARACTER_SA($CharacterContext(),"characterRegeneration");
-tgt = $IndexOf($Myself());
And here's the minimod for the crash. I know a red Dragon is supposed to murder you, but it shouldn't murder you so hard the game crashes...hard
