Guardian Golem

The Guardian Golem is a Master Mode-exclusive light pet-summoning item dropped by the Golem, with a drop rate. When used or equipped, it summons a miniature Golem.

Trivia

 * The phrase in its tooltip, "Power cells not included", is a nod to how most battery-powered toys in commercials and advertisements will warn "Batteries not included", and how Golem is summoned with a Lihzahrd Power Cell.
 * The buff tooltip is a reference to the song "Living Doll" by Cliff Richard and The Shadows. The original lyrics read "Got myself a cryin', talkin', sleepin', walkin', livin' doll". The tooltip has simply replaced "doll" with "idol", as Golem is the Lihzahrdian Idol.
 * When summoned, the pet will always position itself in front of the player. This is likely because it is meant to act as a guardian, hence the name of the item.
