Version 0.28: This article is up to date for the latest stable release of Dungeon Crawl Stone Soup.
When activated it hides its wearer from the sight of others.

Wearing equipment with the invisibility ego grants you the Evoke Invisibility ability, allowing you to turn invisible at will. It requires a decently high Evocations skill to use reliably or for a long duration. No matter if you actually turn invisible, your maximum hitpoints will be temporarily drained. Turning invisible will also cause magic contamination. (See the Invisible article for details.)

The invisibility ego can be found on:

Desirability

Invisibility is a decent ego, giving the wearer the ability to turn invisible without needing to use up a rare potion. Being invisible grants many strong bonuses, such as greatly decreased enemy to-hit, an increased chance for enemies to forget about you or fail to notice you entirely, and the ability to get low-tier stabs.

However, the Evocations investment required for reliable use and fairly heavy drain (a bit more than 8% of MaxHP) discourage using it until you start facing more monsters who can see invisible. Players can try evoking with low skill, but risk getting drained with no benefit.

Success rate rises with Evocations skill:

Evocations Failure rate(%)
0 71.47%
1 67.43%
3 58.88%
5 50.00%
7 41.12%
10 28.53%
15 12.31%
20 3.71%
25 0.49%
27 0.11%

History

  • Prior to 0.28, turning invisible caused more magic contamination initially and applied contamination over time.
  • Prior to 0.26, evoking invisibility caused hunger instead of draining you.
  • Prior to 0.25, invisibility generated on cloaks instead of scarves.
  • Prior to 0.21, removing an invisibility-ego item while invisible did not cost the player extra magical contamination.
  • Prior to 0.20, this ego would let the player turn visible again once invisible, as a way to reduce contamination.
  • Prior to 0.18, this ego could be found on rings.
  • Prior to 0.16, this was called the Darkness ego.
