Improved Counterspell

You are skilled at countering the spells of others using similar spells.

Benefit: When counterspelling, you may use a spell of the same school that is one or more spell levels higher than the target spell.

Normal: Without this feat, you may counter a spell only with the same spell or with a spell specifically designated as countering the target spell.

Endzeitgeist Says: This is essentially required to be even halfway decent at counterspelling - at high levels, this can save your whole group.
