Talanor, the Bright Tower
Artifact - Sage Staff of Lorrynor
The staff is hand-carved from an ancient paueliel tree by by Ealiannë, the Diviner of Lorrynor, who was one the mother’s of the elven people. Personally taught the mysteries of the ether by Lorrynor before the Godling War. She created many magical items that are were used to fight the enemy, although many have been lost to time.
It is a cross between a ring of spell storing and the Preferred Spell feat, however, it learns spells rather than stores them for later use. It can be taught a spell by casting the spell and allowing the staff to absorb the spell. Once, the staff “knows” a spell, it maintains that spell until it is taught a different spell. The staff allows you to spontaneously cast its known spell again by sacrificing another prepared spell of the same or greater spell level. The caster level of the spell is your caster level at the time in which you teach the spell to the staff. You can apply any metamagic feats you possess to this spell when you cast it. This increases the minimum level of the prepared spell or spell slot you must sacrifice in order to cast it but does not affect the casting time. The staff can learn up to a 5th level spell.
