Zombie Skills/Digestion
Digestion is a zombie skill which allows the player to gain HP from bite attacks or from feeding on corpses. It is also the prerequisite skill for Infectious Bite. Like all zombie skills, Digestion costs players of all character clases 100xp to purchase.
Whenever a zombie with Digestion deals bite damage, it gains HP equal to the damage dealt, invariably 4 in both cases. In addition, zombies with Digestion can Feed on a corpse if there is a dead body on same block as the zombie; this costs 1 AP and restores 4 HP, directly emulating the effects of a 'live' bite.
A zombie cannot feed on the flesh of a reviving body – instead, if this action is attempted, the player will recieve the message The body is tainted with strange chemicals. The flesh fizzes against your tongue, and you spit it out. This action will not waste any AP, but at the same time does not gain the zombie any HP.
Likewise, any zombie that tries to feed on a body that has already been fed upon ten times before will receive the message The body has already been picked over, and has grown cold and indigestible. This also will not waste an AP or give the zombie any HP. The count only checks from the time of the character's most recent death, and resets upon standing up – a body fed upon ten times before standing and being killed again will be available to feed upon another ten times again.
Feeding on a body will not pass on an infection, despite the link between bites and infections.
