Corona

Version 0.30: This article may not be up to date for the latest stable release of Crawl.

For the mechanic sometimes referred to as "glow", see magic contamination.

Corona (also known as "glowing" or "backlit") is a status effect and monster-only spell which causes the target to glow with an aura of light.

Effect

The Corona status prevents you from going invisible, reduces your stealth, and makes you easier to hit (attackers gain a to-hit bonus of 1d8 + 1).

This status is negated by being in Dithmenos' Shadow Form.

Sources

Other than the Corona spell, the following sources can inflict the Corona status:

• Evoking a piece from Xom's chessboard has a 10% chance to inflict Corona.
• Ru's Aura of Power may inflict the Corona status on monsters.
• Zin's Recite may inflict Corona on monsters.
• Meteorae have an innate glowing mutation.

The following don't inflict the Corona status directly, but causes the same effect:

• Magic contamination above 5000 (yellow or higher) causes glowing, among other unpleasant effects.
• Setting a target ablaze with Sticky Flame also causes them to glow.
• A halo will backlight all creatures within it.

When you emit a halo, you can't go invisible, but enemies don't get the accuracy bonus against you.

Spell

The Corona spell must have line of fire to the target to cast, and it must overcome the target's willpower to inflict the status.

The following enemies cast Corona:

• e Dowan
• c Faun
• g Gnoll shaman
