This Killer Mimic creature is found within the Watcher's Keep Machine of Lum the Mad area.
This creature can be encountered in Baldur's Gate II: Enhanced Edition and Baldur's Gate II: Throne of Bhaal game versions.
Gameplay[]
The creature is invisible until it attacks.
When a party member is in detection range (about 25' game feet distance) any or all of the four unique mimics will launch their opening spell attack ability.
For this particular killer mimic, it is the Mimic Poison.
The creature will attempt this ability once per round as long as it has a detectable target and is still functional.
This creature is stationary and remains within the container it has infiltrated - mimics have poor defenses, and no special immunities.
Note[]
These mimics possess a melee attack weapon but aren't scripted to use it. They attack with spell abilities of various types, even at point blank range.
