Mastery of Madness
( Player's Guide to Eberron, p. 126)[General]
You have learned to reach magically to the ever-distant plane of Xoriat and draw some element of its madness into the world--but these techniques come with some risk.
Prerequisite
Iron Will (PH) , Knowledge (the planes) 2 ranks, Spellcraft 9 ranks,
Benefit
Whenever you summon a celestial or fiendish creature with a spell, spell-like ability, or magic item, you can choose instead to summon a pseudonatural version of that creature (see the pseudonatural template in Complete Arcane, reproduced in abbreviated form below). When you use this ability, you must succeed on a caster level check (DC 15 + spell level) to avoid opening a small temporary rift to Xoriat, which affects the spell as if it were cast on a plane with the wild magic trait (roll d% on the table on page 150 in the Dungeon Master's Guide to determine the effect). Pseudonatural Creature: Change type to outsider. SA true strike 1/day, S Q alternate form, damage reduction, resistance to acid and electricity, spell resistance; Int minimum 3. Alternate Form (Su): Take form of grotesque tentacled mass as standard action; statistics remain as normal but attacks take --1 morale penalty. Damage Reduction (Su): DR 5/magic (HD 4-11) or DR 10/magic(HD 12+). Resistance to Acid and Electricity (Ex): Resistance 5 (HD 1--7), 10 (HD 8-11), or 15 (HD 12+). Spell Resistance (Ex): SR 10 + HD (maximum 25).
