Phantom mirror

This page is about the item. For the monster-only spell, see Phantom Mirror (spell).

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; it can be recharged by gaining experience. 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).<ref>Template:Source ref</ref>
• "check_willpower" is the same function used for other willpower checks. The power of the mirror is equal to (5 + 3 * Evocations),<ref>Template:Source ref</ref> so check_willpower equals willpower - (5 + 3 * Evocations) + 102 - 1d100 - 1d101.<ref>Template:Source ref</ref> If a target has infinite willpower, check_willpower is set to 100, meaning (100 - check_willpower) = 0.

This means that, if a target has at least 99 + (5 + 3 * Evocations) willpower, you will always get a minimum duration summon.

• Duration class is defined in the Summons page. At 1 duration class, the summon lasts 9 turns.

Strategy

Having a spare ally can be very helpful, especially when you're fighting powerful uniques. You can clone just about any monster, including the likes of the Lernaean hydra and Cerebov.
