Potion of amnesia

A potion of amnesia (unidentified, a "sparkling potion") is SLASH'EM specific item.

Quaffing it will cause you to forget all of the current map, has a 1/3 chance of causing you to forget some level maps, and another 1/3 chance to forget some discoveries. If it is non-blessed, it also may cause you to forget some spells. If it is blessed, it will cure lycanthropy and sickness and give you 51-100 nutrition points. Monsters will throw this at the player, with the same effects.

Dipping into it will damage items. They may rust or lose rustfroofing, lose enchantment, and magic tools and stones become non-magical. The dipped items will become uncursed.

This potion cannot be cancelled.

Dipping the potion into a water source will cause it to become a potion of water in one dipping, without the diluted stage. This preserves the beattitude of the potion, and as such may be used as a source of (un)holy water if an appropriately aligned altar is unavailable.
