Kith of the Harpy Queen
This monster supplement expands the classic harpy with variants adapted to different terrains, sizes, magical influences, and situations. The creatures span a range of challenge ratings, supporting encounters for adventuring parties at different levels. It also includes harpy-themed magic items, spells, and feats, along with options for using harpies as more than song-based predators. The collection features storm harpies, piasa, and other winged threats for fantasy roleplaying encounters.
