Archmage

The highest art is magic - often referred to as the Art. Its most advanced practitioners are frequently archmages, bending spells in ways unavailable to other spellcasters. The archmage gains strange powers and the ability to alter spells in remarkable ways, but must sacrifice some of her spell capability in order to master these arcane secrets.

Requirements

To qualify to become an Archmage, a character must fulfill all the following criteria:
Skills: Knowledge (arcana) 15 ranks, Spellcraft 15 ranks.
Feats: Skill Focus (Spellcraft), Spell Focus in two schools of magic.
Spellcasting: Ability to cast 7th-level arcane spells, knowledge of 5th-level or higher spells from at least five schools.
