A creature that has this feat has studied the alien and disturbing arcane lore of the grell, and understands the magical and physical laws by which their spells and devices function.
Knowledge (dungeoneering) 3 ranks, INT 13, caster level 1st,
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 diffi cult 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 identifi er also knows this feat.
