Libellus Magnus: Metamagic & Counterspells Feats

This d20 supplement adds 20 feats for spellcasters, including a new type: Counterspell Feats. Metamagic options alter spells with effects such as blinding, reducing, or changing their energy, while Counterspell Feats add effects such as deflection and reflection. The game master decides which material to include in a campaign.
