What happens when a bound spell is miscast depends on the nature of the bound spell.

• If the bound spell is contained within a magic item of some kind, the item crumbles to dust and cannot be used again during the game. Do not roll on the Miscast table.
  

• If the bound spell is an 'innate' ability, then the model simply cannot cast further bound spells during this phase. Do not roll on the Miscast table.
