Stained glass golem

A stained glass golem was a type of golem resembling stained glass. They were constructed to blend in with the decor of a temple or palace, in order to hide them from view to all except unwanted visitors.

Construction
To create a stained glass golem, a high-level arcane spellcaster skilled in glass-making required some of glass shards and the spells geas/quest, limited wish, and polymorph any object, and it otherwise cost 10,000 gp.

Description
They resembled flat, two-dimensional imitations of people made from glass. They were silent and never communicated; the only sound they made was a tinkling sound like delicate crystal wind chimes when they moved. As they moved, they flickered and twinkled as the light passing through them refracted.

Abilities
A stained glass golem could of course blend in perfectly with any window.

They were immune to all magic and spells except for sonic spells and the shatter spell. A stained glass golem could be repaired with mending, but healed rapidly on its own.

Combat
They fought by swinging their arms; like broken glass, their edges were very sharp.

Society
They were encountered alone, in pairs, or in groups of up to five.

Usages
Deep within the jungles of Chult, four of these golems were installed by the necromancer Zzarka Tuzarr's within the stained glass windows of her sandstone pyramid stronghold.
