Invisibility (ego)
| When activated, it grants the wearer temporary invisibility, but also drains their max health. |
Wearing equipment with the invisibility ego grants you the Evoke Invisibility ability, allowing you to turn invisible at will. It has a chance of failure, based on your Evocations skill.
Regardless of whether you fail or succeed, your max HP is temporarily drained (~8% max HP). Successfully evoking invisibility will cause minor magical contamination.
Sources
The invisibility ego can be found on:
- Scarves
- The unrand ring of Shadows
- Randomly generated artefacts
Desirability
Being invisible is a strong effect. Against enemies that can't see invisible, it greatly reduces chance of being hit, and allows you to stab. A scarf of invisibility gives all those benefits without needing to use a rare potion.
However, the Evocations required to reliably go invisible is high. And the heavy draining discourages use until you do get enough skill. By then most 'tough' enemies will be able to see invisible. The invisibility ego can still be useful (many weaker enemies don't have SInv), but you may want a more consistent item.
Even in the late game, there are many enemies that can't see invisible. Examples include caustic shrikes, death cobs, draconians, tormentors, and hellions.
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 some 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.
