If you are in a battle where the AI has decided not to uses gems/slaves. And the enemy is fleeing/routing. The AI will start to use slaves again. I lost all my bloodslaves because my spell casters finished the round casting after there was no enemy left. They used slaves even while there was no enemy to cast spells at.

You want to know the funny part. They used slaves casting thunderstrike and strength of giants, Phoenix power, Raise dead etc.
