Magic contamination is a dangerous condition caused by miscasts and some magical effects.
Contents
Overview
Various activities cause harmful magical energies to accumulate in your body. A small amount of magical contamination (a dark or light grey "Contam" status) is mostly harmless, and will dissipate over time without any further effect. Larger amounts of accumulated magic contamination (a yellow, red, or dark red "Contam" status) will make you start to glow with magical contamination.
The glow from severe contamination (>=5) makes you easier to hit and reveals you if invisible, similar to the Corona spell. Over time you may also suffer damage and mutations.
Any amount of contamination can cause ugly things adjacent to you change their colour.
Contamination Levels
| Contam[1] | Colour[2] | Description[3] |
|---|---|---|
| >0 | Dark grey | You are very lightly contaminated with residual magic. |
| 3 | Light grey | You are lightly contaminated with residual magic. |
| 5 | Yellow | You are contaminated with residual magic. |
| 15 | Light Red | You are heavily infused with residual magic. |
| 25 | Red | You are practically glowing with residual magic! |
| 40 | Red | Your entire body has taken on an eerie glow! |
| 60 | Red | You are engulfed in a nimbus of crackling magics! |
Sources
Spells
- Disjunction: 0.75 to 1.25 per cast[4]
- Irradiate: 1.25 to 2 per cast
Miscasts
- Every miscast: Amount depends on severity etc.[5]
- Transmutations miscast: Doubles current contam
Other
- Invisibility (ego): (?)
- Removing an artefact with *Contam: 7[6]
- Mutagenic fog: 1.3 to 2.55[7]
- Zot trap: 7 to 20 (one of many possible outcomes)
- Jiyva penance: 0 to 0.5 * penance[8] (one of many possible outcomes)
Dissipation
Magic contamination is dissipated at the rate of 0.075 per turn.[9]
Quaffing a potion of cancellation removes 1 to 5 points of contamination.[10]
While being severely contaminated every 200 to 600 turns[11] there is contamination / 12[12] chance of a violent release of energies. Standing in a sanctuary stops this from happening.
One likely bad mutation (about 95% chance) is gained that bypasses mutation resistance. If contamination is higher than 10, there is also a damaging explosion. The damage is 3d(contamination / 2), and doubled for the non-living. Explosion size also increases with the contamination level. After the negative effects contamination is reduced by 1 to 1 + (contamination / 4)[13].
Tips & Tricks
Being in lichform, by way of Necromutation, prevents any contamination-related malmutations; instead, your stats temporarially rot.
History
- In 0.29, the level of contam for the light grey warning was decreased from 3.5 to 3, to match Irradiate's increased contam.
- Prior to 0.28, the Orb of Zot extended contamination, and invisibility caused contamination over time.
- Prior to 0.26, magic contamination decayed much slower: -0.025 per turn instead of -0.075. Also, reading a scroll of blinking contaminated the player.
- Prior to 0.25, miscast effects were different and thus had different contam levels.
- Prior to 0.20, drinking a potion of haste and the haste effect contaminated the player.
- Prior to 0.19, the light grey contamination level didn't exist.
- Prior to 0.10, this effect was simply called glow, a term which ambiguously referred either to magic contamination, or to the relatively harmless glow from Sticky Flame or Corona.
