You have learned how to burn a wand up by applying your metamagic feats to it.
Benefit: You can apply one of your known metamagic feats to the energy of a wand’s effect. This does not increase the effective level of the spell but does burn an additional number of charges equal to the effective spell level penalty required to use the metamagic feat.
