What are the ON/OFF spells?

All I need is a simple list of the spells that can be turned on and off. Preferably ones without side effects (like magic defense makes the unit invulnerable to magic, which is bad ><) The spells I'm talking about are the ones that you turn on and off at will, not turn it on, then you ca turn it of before the duration ends if you want. All I have so far are:

Immolation ( )
Magic Defense (X)

(X means tested and unsuccessful)

Thanks to anyone who contributes!

Divine Sheild if its Rigged properly. Defend. I THINK Spiked carapace can be converted to its original on/off.

mana shield

Open a map, select Advanced on the toolmenu, select Gameplay Constants, and scroll down until you see Gameplay - Can Deactivate Avatar. Including and following that entry is a list of abilities that can be activated, and the value of the constant determines if the ability can be deactivated.

In the beta version of RoC you could also deactivate avatar.
