Grell Alchemy

 
Prerequisite(s): Knowledge (dungeoneering) 3+ ranks, Int 13+, caster level 1+.
 
Benefit: A creature with this feat can create grellcraft items, including lightning lances. Its spells are partially based on obscure physical laws, as opposed to magic alone, and therefore gain a +2 bonus on spell penetration checks. They are also more difficult to identify or dispel. Spellcraft checks made to identify the spells and caster level checks made to dispel the spells are made with a -2 penalty unless the identifier also knows this feat.
