Fundament Spell (Feat)
You can weave the fundamental principles of reality into the very fabric of your spells.
Prerequisites: Caster Level 16, Element Spell, Rudiment Spell
Benefit: At the time this feat is chosen, you choose one energy type from the list of rare energy damage types (Rare (Darkfire, Eldritch, Freezacid, Holy, Quiescent, Soul, Stellar, Sunlight, Tenebrous, Threnodic, Thundercrash, Void)). You may replace a spell's normal damage type with that energy type so it inflicts all damage in the new type, instead of the damage type it normally deals. Once chosen, this damage type may not be changed, except through the re-selection process.
Special: You can gain this feat multiple times. Each time the feat is chosen, a different rare damage type may be selected.
Level Increase: +2 (A fundament spell uses up a spell slot two levels higher than the spell's actual level.)
