Maw Mad Construct

Maw Mad Construct is an abomination leftover that frequently spawns in Perdition Hold during the Necrolord Assault. It drops another Quartered Ancient Ring necessary to craft the Nilganihmaht's Stone Ring, one of five to create the Nilganihmaht Control Ring crawling hand mount in The Rift.

It spawns and yells a few random lines:

• yell
• yell
• yell

The construct runs along one of two fixed routes, spawning around and ending at inside the building, or at by Seeker Xeros. Like Treasure Goblins, the construct cannot be stopped and will continue running to the targeted point, where it despawns.

Defeat it:

• say

• Quartered Ancient Ring

• Its quotes about the "priceless" is a reference to, from the ' and '. Gollum refers to the (and himself) as "precious".
