Rod of Foiled Magic

Ultimate Equipment
Aura: Strong (no school)
Caster Level: 17th
Weight: 5 lbs.

This rod is similar in appearance to a metamagic rod. Once a creature picks up such a rod, it cannot be discarded without use of a calm emotions spell or similar magic. Each time the wielder casts a spell, he takes the rod of foiled magic in hand and treats the caster level of the spell as 2 levels lower. If this would reduce the caster level to 0 or lower, than the caster has only a 50% chance of casting the spell (any chance of arcane spell failure is added to this percentile chance), but if he is able to cast the spell, the spell has a caster level of 1st.

Intended Magic Item

Any metamagic rod
