Polished Quartz

A special stone that is able to store spells cast into them. While holding the stone, you may cast a spell of the corresponding school (eg. Fireball, an evocation spell, into a Red Polished Quartz) and the spell will be stored in the stone until a new spell is cast in it or the original spell is dismissed.

When a spell is cast into the stone, the spell has no effect other than to be stored into the stone. If the stone cannot hold the spell, the spell is expended without effect.

Once a spell has been stored into the stone, anyone aware of the spell inside and holding the stone may cast the spell in it. The spell uses the slot level, spell save DC, spell Attack bonus, and Spellcasting Ability of the original caster, but is otherwise treated as if that person cast the spell.

The spell recharges at the next dawn.

* Purple quartz is commonly referred to as Amethyst
