Character gains the ability to nullify offensive spells used against them. This ability is always active. The chance of successfully negating the spell is dependent on the Wizard's knowledge of the spell in question:
- If the character knows the base spell and the spell is not modified by Taint Spell, Sanctify Spell, or Deep Spellcraft, it is automatically countered.
- If the character knows the base spell and has Deep Spellcraft, the spell is automatically countered even if altered via Deep Spellcraft.
- If the character knows the base spell and the spell is modified by unknown means, whether Deep Spellcraft, Taint Spell or Sanctify Spell, the character has a 66% chance to counter the spell.
- If the character does not know the spell, the wizard still has a chance of countering it. This chance is equal to half the chance the wizard would have had if they had known the spell.
Successfully countering a spell charges the Wizard 1 MP, but failure does not cost anything. The wizard cannot counter a spell if they don't have any MP remaining.
