Block Spell
Metamagic feat
Block Spell is a D&D 3.5 feat (Metamagic) from WoW, p. 143. You may channel magic energy to block the effects of a spell.
Prerequisite
Iron Will, Magic Energy Control, caster level 5th.
Benefit
When you are the target of a spell, you may disrupt the casting and counter its effects. Make a Spellcraft check (DC 15 + the spell's level); this is a free action, and it does not require a readied action. If you succeed, you identify the spell and may automatically attempt to counter it according to the normal counterspell rules.
