I am looking at creating wands that can cast from a type of spell. for example. Wand of healing. This wand can cast all the Clerical healing types of spells. Cure Light Wounds, Cure Serious Wounds, Cure Critical Wounds, Cure Blindness, Cure Disease, Heal, Neutralize Poison and Regenerate.
The spells involving the dead are not included.
For Clerics and non-Clerics except Fighters (Fighter classes cannot use the wand), the wand has 50 charges and each spells consumes as many charges as the spell level. ie a seventh level spell like Regenerate costs 7 charges from the wand.
The wand can only be recharged by a Cleric of sufficient level to cast 7th level spells and prays consistently for 7 days straight for a 75% chance the deity will recharge the wand. (rolled on the 7th day of prayer)
The cost to re-charge such a wand is 10,000 GP per highest spell level (70,000 GP) and a promise of a quest on behalf of the Cleric and/or Deity who re-charged the wand.
Still working on similar wands.
