Sentinel's Mark
Version 0.14: This article may not be up to date for the latest stable release of Crawl.
Sentinel's Mark is a monsters-only spell that attempts to temporarily afflict you with the Mark condition, causing all monsters on the current floor to know your location and seek you out. Sleeping monsters are not affected by this until they wake up. Characters with high magic resistance may negate the effect entirely. Its spellpower doesn't depend on the attacker's HD. It is always 125 (78 after stepdown). Characters with at least 178 MR are immune to this enchantment.
Quaffing a potion of cancellation will cancel this status effect.
You may also acquire the Mark condition by stepping on an alarm trap. This effect ignores your magic resistance.
The following monsters can cast Sentinel's Mark:
