Hello everybody!
Here Spell Storing weapon description: "A spell storing weapon allows a spellcaster to store a single targeted spell of up to 3rd level in the weapon. (The spell must have a casting time of 1 standard action.) Anytime the weapon strikes a creature and the creature takes damage from it, the weapon can immediately cast the spell on that creature as a free action if the wielder desires. (This special ability is an exception to the general rule that casting a spell from an item takes at least as long as casting that spell normally.) Once the spell has been cast from the weapon, a spellcaster can cast any other targeted spell of up to 3rd level into it."
My question is about the last sentence. When a spellcaster castes a targeted spell into a weapon, is this a standard action or a free action?
Thank you
Casting the spell into the weapon is a standard action. Releasing it is a free action.
That means you're generally going to want to store a spell before combat, but not during combat.
