Balt announced clearly that 'I am going cast spell to halt it, attacking it will break the spell effect'. Also everyone acts before the monster despite initiative order, however Balt is first to act in initiative and everyone acts after him in combat. So that's why I considered it important to announce the spell effect IC and now in OOC as he is first to act in given turn.<br/><br/>Of course it can be bit awkward to stand and wait what happens so I suggested you can ready actions to attack the undead if Balt's spell does not stick. Also I gave a nice visual of 'golden heavenly chains' locking down on the undead (it's entirely fluff purpose and normal spell has not that flashy visual probably).
