Lycanthropy

Lycanthropy is an intrinsic conveyed by being bitten by a werecreature - a werejackal, wererat, or werewolf. It is also conveyed by eating the corpse of one of the above. The message "You feel feverish" is displayed upon acquiring the intrinsic.

The intrinsic transforms you into the animal form at regular intervals. Quaffing a potion of unholy water will do the same. While in were form, you can summon jackals, rats, or wolves as pets.

Lycanthropy is generally considered intrusive as animal forms tend to get burdened to overtaxed by inventory that was no problem before. Werewolves, in addition, will destroy their shirt, cloak, and body armor when transforming to animal form. To remove lycanthrophy, you can pray to your god, eat a sprig of wolfsbane, or quaff a potion of holy water. If none of these options are available, an amulet of unchanging or ring of polymorph control will keep the intrusive changes under control.

To prevent lycanthropy, you can wear a ring of protection from shape changers. Magic cancellation reduces the chance of catching lycanthropy when bitten.

Pets summoned by using the #monster command will remain tame after you have returned to human form, or if you become cured. A very large number of pet jackals, rats, or wolves can be aquired by summoning help over the course of several transformations to the were form. These pets will be very weak, however.

Strategy

Lycanthropy can be beneficial as it confers drain resistance. If you have polymorph control (from wearing or eating a ring of polymorph control or in SLASH'EM choosing the doppelganger race and reaching level 9) you may choose not to transform into your were form, leaving no adverse affects.

SLASH'EM

New lycanthropes in SLASH'EM include werepanthers, weretigers, werespiders, and weresnakes.
