Morphologies

Rookey adapts to the world’s biomes, taking on a different form in each region — its own look, habitat and story, and often its own element typing (a highland or stormy population can pick up a second element the basic form doesn’t have). The base statline is shared. Switch between forms with a Morph Orb. Tap a pod to reveal each one.
