During the First Age, many followers of Orlanth HeroQuested and travelled back to his victory over Yelm. There they found the method to create Thunder Arrows.
To create the Thunder Arrows, the Orlanthi must perform the "Orlanth Slays Yelm" HeroQuest and must take one or more of the arrows fired at him during the fight. If no arrows were fired at him, he may not create Thunder Arrows. He must then use the Create Thunder Arrow spell on each arrow to create a Thunder Arrow.
A member of the Thunder Arrow Magic Weapons Subcult may use Thunder Arrows created by another member by sacrificing 1 POW per point of the Thunder Arrow.
Once used, the Thunder Arrow is de-activated and must be re-activated using the Bless Thunder Arrow spell.
Thunder Arrows are also more expensive to create and may only be created at the culmination of a HeroQuest. They may only be re-charged and created by members of a small Magic Weapon Subcult of Orlanth which is only found in certain Great Temples.
The following spells are available from a Thunder Arrow magic weapon subcult whose members only include those who have successfully performed the "Orlanth Slays Yelm" HeroQuest.
Create Thunder Arrow (Stackable, 1 Use, Permanent, Ritual Enchant)
This spell may only be cast at the culmination of the "Orlanth Slays Yelm" HeroQuest by the Orlanth of the HeroQuest.
The caster must have collected arrows fired at him by Yelm during the Quest. He then casts the spell and attempts the Enchant roll. If the roll is successful, he loses 1 POW per point of spell and enchants the Thunder Arrow. In any case, he uses the spell and must re-sacrifice if he wants to create more in the future.
The Thunder Arrow created will act as a Thunder Stone when fired as detailed above.
Bless Thunder Arrow (3 point, Reusable, Permanent)
This spell may only be used on a Thunder Arrow which has been used. It charges the Thunder Arrow so that it may be used again. The spell has no effect on a Thunder Arrow which has not been attuned to the caster.
