Spell Interruption Rate

When a mage casts a spell, there is a chance the he may be interupted before the spell has been completely cast. He can be interupted by being hit by an enemy, or moving around. You will have a higher chance of not being interupted if you are casting on a significantly lower level mob than yourself. There are also some items that can lower the chances of spells being interupted.

Any class that uses magic has a chance of being interupted, including Ninjas and Bards. Bards, however, are special in that they can on be interupted by moving. Normal mob attacks will not interupt a Bard.
