Slack-Skinned Head

The Slack-Skinned Head and Mind-Archive Interface can be found side-by-side in the Mind Flayer Colony after defeating a Death Shepherd, some winged horrors and various Zombies.

Involvement

Various 'minds' in green jars can be found and inserted into the Mind-Archive Interface, which lets the player have a conversation with the unfortunate creature via the Slack-Skinned Head.

There are 2 minds to be found on the Nautiloid in the Prologue:

• Dark Mind
• Slave Mind

There are 6 minds to be found within the Mind Flayer Colony in Act Two:

• True Mind - in front of the head in the Necrotic Laboratory.
• Willing Mind - on a desk west of the head in the Necrotic Laboratory.
• Butchered Mind - on top of a set of shelves with discarded armour, in the Morgue where Chop works.
• Closed Mind - on a shelf in Ironfinger's room, in the north-western part of the Barracks.
• Fresh Mind - on-top of a stack of mucilaginous boxes beside the elevator leading to the final area.

This mind is unique because speaking to the head can grant the permanent buff Githzerai Mind Barrier:

• Waking Mind - is behind a door in the Necrotic Laboratory, only accessible after solving the brain mapping puzzle.
