You can use a spell you know to undo an enemy's spell that is currently active.

• Your spell must be either exactly the same spell, or a natural counter to said spell.
  • For instance, you can dispel Fireball with Fireball, or perhaps you can dispel it with Water Sphere.
  • Natural counters are subject to DM adjudication.
• You must roll a Spellcraft check against the spell's DC:
  • If your roll is greater, the enemy spell ends immediately.
  • Else, no effect.
• Your spell has no effect other than to attempt to dispel. It still has normal Mana cost, casting time, range, etc.
• Your spell must have the same or greater Mana cost as the spell you are dispelling.
  • If your spell costs less Mana, you suffer a -10 penalty to Spellcraft per point of Mana difference.
