It's only me or everyone here thinks the spell storing ability the best ever?
Spell Storing: 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. The weapon
magically imparts to the wielder the name of the spell currently
stored within it. A randomly rolled spell storing weapon has a 50%
chance to have a spell stored in it already.
It's mean that the fighter of my group can store a spell in his sword with scoching ray every turn with the mage, taths mean this ability is overpower. Or am I wrong? Please help me to balance my game...
