Sink

Sinks are a dungeon feature represented by a #. Sinks will cause anything in the air above them to fall to the floor, be it thrown weapons, or your levitating character. Falling into a sink while levitating will damage your hit points, and might even cause death. Kicking a sink or quaffing from it has consequences, most of them negative, with a few beneficial ones. Dropping rings into a sink will cause them to be lost down the drain, with a message that enables you to identify the ring.

Kicking a sink

Kicking a sink has several possible effects.

80 percent of the time, "Klunk! The pipes vibrate noisily." This exercises dexterity.

Once per sink, "A black ooze gushes up from the drain!" A black pudding is summoned, and dexterity is exercised.

Once per sink, "The dishwasher returns!" The dishwasher is a foocubus of opposite sex to the hero, or of random sex if the hero is a neuter creature. Dexterity is exercised.

Sometimes, "Flupp! Muddy waste pops up from the drain." Once per sink, when this happens, "You see a ring shining in its midst" and dexterity and wisdom are exercised.

If none of these things happens, "Ouch! That hurts!" You lose up to 5 hit points, abuse dexterity and strength, and possibly end up with a wounded leg.

Quaffing from a sink

You can drink from a sink by using the quaff command while standing over it. Upon doing so you get a message hinting at the resulting consequence. The specific message you recieve is dependant upon your status and the condition of dungeon monsters.

Identifying rings with a sink

All rings may be identified by dropping them into sinks. The sink will show an effect depending on the type of ring. Ring other than searching and slow digestion will be lost with 95% probability; therefore it is a good idea to do this test only if you have another ring of the same type as the one being tested.
