STOP Spell

The only two checks for stopping a spell is that it is defensive and that you can cast it. Some offensive spells can be stopped, Breeze (612) being an example; others use different verbs (Tangleweed (610) uses DISMISS). Minor Sanctuary (213) can by stopped by anyone who has incanted it via scroll, blessed gem, or other method.
