Scarecrows might not seem as tough as the other monster races, but they are really hard to hit with anything other than fire and are immune to most conditions. I looked to the Scarecrow from the Monster Manual and the Warforged race from Unearthered Arcana for ideas. A Scarecrow PC could have died and their spirit was trapped in a scarecrow, until their master died and no one was left to control them.

Scarecrows are spirit-powered constructs that silently guard fields awaiting harvest, bound by the command of their master. I’d recommend staying away from lower levels as many of the weaknesses of these races will get a low level PC killed with one hit and the super charged racial traits will be exposed more at lower levels. That being said, they do a decent job on recreating monster abilities to provide as player options for a Halloween one-shot. Their traits are more numerous and powerful than race options from the Player’s Handbook and they have weaknesses too, which is all very un-fifth-like design. These racial options are far from balanced. Let your players mix these with any class and background to create a their own unique monstrous player characters.
