Trick or treat

From NexusWiki

In honor of Haloween, you may say "trick or treat" to any innkeeper.

Tricks include losing your gateway spell, scrolls, and return spell and being sent to a corner in vale, changing face, changing totem, casting mass vertigo, being sent to a jail (no punishment or loss of karma), and summoning rabbits.

Treats include watermelons, karma, special dyes, and multiple morphs.
