Brogue Wiki

Hallucination is a status that can only affect the player. It causes all monsters to appear as random, constantly shifting letters; You cannot tell what an item is until you step onto it, and all status information about monsters except their health is removed from the sidebar. This is accompanied by a variety of other colourful visual effects.

Hallucination seems at first to be a joke, but removes from you many vital sources of information about what you're fighting - what they are, their status effects and what mode they're in (sleeping, wandering, hunting, etc). For instance, you may corrode your equipment on an unknown acid mound, split an unknown pink jelly in the middle of a room, pop an unknown bloat and have nowhere to run from its effects, wake up a monster only to find out it is an ogre that happily clobbers you to death, et cetera. As such, hallucination should be waited out in safety whenever you are unconfident about your chances.

Although you cannot tell allies from foes while hallucinating, you will still displace rather than attack allies that you walk into, and staves and thrown items will still pick appropriate default targets. If the shifting colours make it difficult for you to identify terrain and gases, disabling visual effects with "\" can help. This does not provide any additional information but makes the screen easier to interpret and saves having to hover over terrain with the mouse.

It is caused by Potions of Hallucination (300 turns) and toads (20 turns per hit). The ability to inflict hallucination cannot be learned by allies. Hallucination can be waited out or can be cured by quaffing a Potion of Life.


Visualize a figure by hovering over it.

Inanimate figures are simply identified by sight.

To identify a jackal or wraith,
Depth 2-7:
Jackal: The figure moves twice your normal speed and is in packs.

To identify a member of a bloat or a vampire bat,
Depth 2-13: Visualize the figure and if it is floating and doesn't appear in packs, (visualize the neighboring creatures) it is a bloat, else a vampire bat.

To identify a member of a goblin,
The figure should be near a orange ϙ symbol i.e. a goblin totem. The goblin is worshipping.

To identify a toad,
The figure refuels the hallucination bar.

To identify a member of an ogre,
The figure does not attack on the turn after he hits you. The figure should be near a green ϙ symbol i.e. a ogre totem. The ogre is worshipping.

And if you are unknowingly screwed and got nowhere to run, see how to escape a cornering.
