Arkham Horror
Can you cast a spell during an attack action, such as Wither, and can you cast more than one?
A spell whose text says it is part of an attack action can be cast as part of that attack, and you can cast more than one if your hands allow it. If a spell kills the target before the attack roll, the roll is skipped. The timing around the attack roll depends on the spell's wording, so read the card; the rulebook sets no order.
