Paladin Primer Bug.. maybe

[Redhawk]

Last night Maev was slaying undead -- as usual -- and her own bless weapon spell wore off while she was surrounded by specters.  Needing a boost to get out, she cast bless weapon from her primer and for some reason it didn't use a vial of holy water.  She donated the unused one to the temple of Roferien, but how can you bless a weapon without a vial of holy water? thanks, redhawk

Casting a spell from a scroll, wand or item does not use a component.

iirc its the same way in PnP though you need the components at the point when you craft the scroll/wand/item.  The logic being whatever power the component provides is incorporated into the item on creation so you don't need it when you use it.
