Symbionts are creatures capable of living independently but preferring to incorporate their physical existance into a host creature, occupying part of the hosts body. Soul ticks are infernal arachnids that attach their bodies to a hosts skin and feed on their blood, enhancing death and evil spells and protecting the host against chaotic or good spells. These increase the hosts CR by +1.
