Concealment

The caster discreetly removes any visual or audio affects a buff or healing spell may have on a target. This spell allows the caster to cast certain spells without having the spell being casted or the method of casting, being noticed.  It does so my creating an illusion of a still mouth and still/empty hands.

 The caster must succeed on a Sleight of Hand check and cast the spell prior to the spell they wish to conceal.
