If your spell is in anything you say, it becomes a failure, although if you try using it while talking, it doesn't work.
Example:
Spell name: a
If I say anything with an a in it, what I say become a spell failure. >_>
Although if I try saying things without a, then add the a to the end it doesn't work as a spell.
Example: Die! a amberrune
Lone Wolf failed to cast a spell.
Try it.. it's fun.
Edit:@Kyphis what if a player's name was came a spider.. would the spell activate on yourself or on him.
Edit2:@MoM my spell had the letter V, and if I had typed it I would be unable to talk, there is no armeagaden >>
