Of the many kinds of felldrakes, few are as powerful as the spiked felldrake. Its size and strength place it in the frontline of important battles, and some mighty knights or paladins employ the spiked felldrake as a steed.

A spiked felldrake can stand up to terrible punishment while dealing out plenty of its own with swordlike claws. The spikes on its tail are not just for show - it can project them in a hail of deadly fire at approaching enemies. With its scent and vision abilities, a spiked felldrake can root out even hidden enemies reliably.
