You can create Illusions. An illusion lasts: 1d6 rounds for levels 1-5; 1d8 rounds for levels 6-10; 1d10 rounds for levels 11-15; and indefinantly for the remaining levels.
An illusion can't really harm a person, it is all in their mind after all, if they realize that your images are fake, any "harm" inflicted on them is negated. They must beat with a 1d20 Intellegence save a score of 15 + (1/2 your level rounded down).
The more bizarre an illusion (i.e. a dead person come back to life; a giant 6 headed toad etc.) the more likely they are to get a bonus because of logic. Small children do not get logic bonuses.
