Wizard's Spontaneous use of Metamagic Feats????

[thullgrim]

In our game we went to a spell point system, with a Spellcraft check to cast. Meta-magic feats add to the DC to cast as well as to the amount of mana needed to cast. Failing a spellcraft check is not pretty as it results in 1point abilty damage per spell level of the failed spell. The ability point damage is not healable by lesser restoration, but time, restoration, and wishes all work. All spells and meta-magic feats are spontaneous.
