Sense invisible

Obsolete: This article refers to an aspect of the game which has been removed. It is retained for historical reference only.

Monsters which "sense invisible" can tell where invisible opponents are, and have bonuses to perception in other cases.

Effects of monster sense_invisible:

• For anything that just checks you.visible_to(monster), it's as strong as see invisible.
• Monsters with “sense invisible” have a better chance of noticing stealthy players than those with “see invisible”.
• “sense invisible” has some effect on a monster guessing an invisible foe's position: Without, it guesses within radius 2 around itself, with within radius 3. This makes it easier to escape from non-sensing monsters, but apparently makes sensing monsters less likely to guess your position when you're close (within radius 2) of them.
• Slightly decreased stabbing chance.
• An effect on beam targeting fuzz

History

• In 0.16, sense invisible was removed and replaced with see invisible and blindness immunity.
