Elemental Lore
A bestiary supplement focused on elemental creatures and related outsiders, including beings associated with earth, air, fire, water, sonic energy, cold, acid, and electricity. It expands classic elementals with nobles, guardians, and haunts, alongside dragons, mephits, and other creatures designed for roles such as grudge monsters and chase monsters. The book includes more than 30 new elementals, six creatures with elemental sub-types, and four new prestige classes for incorporating the elemental planes and their powers into a campaign.
