Elemental Powers Player's Sourcebook

This player-focused sourcebook expands the Elemental Lands setting, where diverse races and cultures emerged after the peoples of the world were freed from draconic rule. It supports varied character concepts, including goblinoids, werecreatures, giants, and other races with the Game Master's approval. The book also encourages incorporating prestige classes, feats, spells, and other material from compatible d20 sources. Dragons and half-dragons remain restricted as rare non-player characters and encounters because of their importance to the setting's history.
