Spellsteal

You attempt to steal an effect from the target, removing it from the target and applying it to yourself for the same duration, provided you meet the requirements (if any). You must pay mana equal to the effects original mana cost. Effects granted through stances, transformations and permanent effects cannot be stolen. After stealing an effect, you can’t use this again until the stolen effect has ended. The stolen effect also cannot be re-applied on the target until it has faded from you. You must have seen the effect be applied or otherwise identified an effect before you can steal it.
