Version 0.30: This article may not be up to date for the latest stable release of Crawl.
This page is about the item. For the monster-only spell, see Phantom Mirror (spell).
Type Miscellaneous item
Name Phantom mirror
Icon Phantom mirror.png
A hand mirror which can create a reflection of a nearby creature, clouding in the process. The reflection's duration increases with Evocations skill and decreases with the willpower of the target. It is, invariably, slightly weaker than the creature it mirrors.

Evoking a phantom mirror allows you to summon an exact duplicate of a single non-player target. The illusion spawns drained, with only 2/3 of the base HD of the mirrored monster. You can use the phantom mirror on any non-tentacle creature in the game. The illusion's duration increases with your Evocations skill and decreases with monster willpower, with a minimum of 9 turns.

The mirror becomes inert after one use and can be recharged only by gaining experience while it is in the player's possession. Like with other miscellaneous evocables, only 1 phantom mirror will spawn in a given game.

Duration

Specifically, an illusion's duration can be calculated as follows:

  • Duration class = (Evocations/4 + 1) * (100 - check_willpower) / 100, with a minimum of 1 duration class (this is not equal to turns).[1]
  • check_willpower is the same function used for other will checks, and is equal to (5 + 3 * Evocations) - willpower + 1d100 + 1d101 - 102. If a target has infinite willpower, check_willpower is set to 100, meaning (100 - check_willpower) = 0.
  • Duration class is defined in the Summon page. At 1 duration class, the summon lasts 9 turns.

Strategy

You can create clones of very powerful monsters, such as the Learnaean Hydra or Cerebov. A spare ally can be very helpful, especially when fighting powerful uniques.

History

  • Prior to 0.26, phantom mirrors were one-use items and didn't recharge with XP. Also, it was impossible to create copies of enemies hated by your god.
  • Phantom mirrors were added in 0.16.
