Easy POP capture
If you are playing a quick battle, choose a Tornado spell and an Ancour spell. Walk up to a POP (place of power) that is guarded by an enemy. Cast Ancour on yourself. Then, cast Tornado on the POP. The enemy should fly away and the POP left clear for you to capture.

Crossing the bridge
In labyrinth level is a "bridge". If you walk across it, you will be teleported to the pit below. To cross the bridge, do not walk over the markings or symbols on it.

Subversion without the spell or pipes
Get a creature with a "crown" over their heads. If they attack an enemy creature of the same species they might be able to subvert it. This also works against illusions.

Destroying totems
The following four spells can be used to destroy totems: Apocalypse, Lightning, Meteor Strike, and Storm.

Killing undead
Summon a Unicorn. They have decent HP, mana cost and are effective against the undead. However, they are not very good against Champion Chaos and Vampires.

Killing mid-air creatures
If a creature is flying in mid-air (for example, a Bat or Griffin), cast the spell Gorgon Stare on them or command a Champion Law to freeze them. They will plummet to the ground and shatter into pieces.
