Wildstrike

This spell is used primarily against hostile spellcasters. It distorts all attempts at spellcasting, converting spell energy into wild surges.

The victim of a wildstrike is allowed a saving throw; if successful, the spell has no effect. If the saving throw is failed, the target is enclosed within a field of wild magic. If the victim casts spells or uses a charge from a magical item, a Wild Surge is automatically created. When determining the effects of this surge, the true level of the wild mage who cast the wildstrike is subtracted from the die roll, making the effects of the wild surge more likely to affect the victim.
