Adding the spellfire elemental template
Spellfire Elemental (template)
Size and Type: Same as base creature, with the addition of the [elemental] and [spellfire] subtypes
Special Attacks: A Spellfire Elemental retains all special attacks of the base creature, and gains the following:
Spellfire (Su): A Spellfire Elemental may generate spellfire as a creature with the Spellfire Wielder feat with the same number of levels as the elemental has HD. In addition, a Spellfire Elemental automatically knows a number of Spellfire templates equal to half it's HD.
Special Qualities: A Spellfire Elemental retains all the special qualities of the base creature, excepting spell-like abilities, and gains the following:
Spellfire Absorption (Ex): If a Spellfire Elemental is the target of a spell, spell-like ability, psionic power, or psi-like ability, the Spellfire Elemental instead absorbs the effect as stated in the Using Spellfire rules (treat psionics as magic for this effect), and also gains 1d6 hitpoints for every spell/power level the spell/power had.
Spellfire Infusion (Su): If a Spellfire Elemental can cast spells, the spell treats the target creatures SR as if it were a number of points lower equal to the Spellfire Elemental's HD. In addition, any effect that causes a direct, numerical effect on hitpoints produces half of it's effect as spellfire, which means it ignores SR and Elemental Resistances. Finally, a Spellfire Elemental Spellcaster can convert any unused spell slot into spell levels for it's Spellfire special attack.
Ability Score increases: +4 constitution; -2 charisma, wisdom, or intelligence (Only reduce the ability that is used as the main casting stat; otherwise, do not reduce any of those three ability scores as a result of this template.)
Environment:
Organization: Same as base creature
CR:
LA: +2
Does that seem sufficient? I've been working on Spellfire templates, and will stick them up here later.
