Does the Extra Spell Feat allow a spell caster to gain access to a spell off another spellcaster spell list?
Can a Warmage who casts specific spells (mostly evocation, conjuration and some necromancy and transmutation) off the Wizard/ Sorcerer spell list to learn Assay Resistance if he takes the Extra Spell feat?
It is on the Wizard/Sorcerer spell list, but not on the Warmage Spell list. The feat specifically states that it designed to allow a spellcaster to learn a spell that they normally would not have access to or the ability to research.
