Physical Shield Maxed-Prevents hits, good for getting high combat multiplier

Slow Time Maxed-Brilliant for dealing with fast enemies like minions

Assasin Rush Maxed-Bypass enemy blocking, which wastes time and thus prevent CM from going down.

I use these three only when fighting. This 3-spell combo works superbly with everything and in my experience is absolutely the best for getting an insanely high combat multiplier. Never got hit in the game except for Bargate Prison which can't use spells at.
