Divine Countermagic

(Faiths of Eberron, page 146, DnD 3.5)

[Divine]

You channel divine energies to counter spells.

Prerequisite

Ability to turn or rebuke undead, access to Magic or Spell domain

Benefit

You can counter someone else's spell by expending a turn or rebuke attempt, rather than casting a spell. You must spend one turn or rebuke attempt, plus one additional turn or rebuke attempt per level of the spell being countered. In all other respects, including using a ready action and identifying the spell with Spellcraft, this ability functions the same as a standard counterspell attempt.

Normal

To counter a spell, you must use dispel magic, or the specific spell being cast.
