Usage:
cast undo <spell name>

The 'undo' spell is used to undo or take down spells affecting you.
It can only be cast on yourself - other people can not help you take down
spells that you want to get rid of.

Your chance of taking down a spell depends on the level of the spell you wish
to undo, your casting level, and how well you know the spell in question.
If you don't know the spell at all, it can be very difficult to undo it.

The mana cost for this spell is approximately half the mana cost of the
spell you wish to undo.
