Note: A 'Weaken Nonmaterial Beings' spell will pass through a Materializer when it is not in a materialized state. However, you can still kill them whith this spell when they are not materialized if there is a wall behind them on which the spell will explode and cause damage to the creature. The 'Disrupt' attack of the Vorpal Blade always works on a Materializer even if it is not in a materialized state.
