Autocast spells casting OUT of combat

Ive been having a little trouble making an autocast spell (based on Bloodlust currently, using Innerfire on/off strings) that will autocast outside of combat. If anyone has any ideas, help would be much appreciated.

Since the point of the game is to make an army that's good at combat, most of the spells are designed to be used for that.

The only spells that come to mind at the moment that are autocast outside of combat are the Priest's Heal and the Dryad's Dispel. Obviously, though, they have rather specific situations where they are castable.

Most, if not almost all, autocast spells only work in combat, when an allied (or yourself) unit is engaged in battle. However...

Carrion Beetles (or whatever it's called, for the Crypt Lord), Raise Dead (Necromancer), Mana Touch/Touch of Blight (the heal/mana on Undead Obelisks) are 3 that are autocastable; however, the first 2 are corpse-only, and the 3rd don't take targets.
