Shardsoul

Shardsouls were crazed constructs that would accompany the Warlock Knights of Vaasa in battle. Human-sized variants were often called shardsoul slayers while larger and more powerful variants were called shardsoul avatars.

Description
Shardsouls' bodies were made of ironfell harvested from the primordial Telos. They appeared as monstrous automatons made of dull crystallized metal, and were notable for their claws. Each shardsoul was animated by a piece of Telos's soul.

Abilities
A shardsoul's ironfell body was as hard as steel. They were unaffected by diseases or poisons, and did not require food or rest. When a shardsoul was slain, its body would crumble, and shardsouls nearby would be momentarily energized by the release of its animating spirit.

Shardsouls were deranged, and this derangement was infectious. They exuded an aura of madness that caused their enemies to turn on each other.

Larger and more powerful shardsouls could fire beams of radiant energy at targets up to 50 feet (15 meters) away.

Behavior
Shardsouls were constantly tormented by a feeling of separation from Telos, and as such were known to be more unpredictable than most constructs, sometimes bordering on apparent madness. This made shardsouls unreliable as workers, but aggressive and eager combatants. They were aware that, if destroyed, their essence could finally be reunited with the main soul of the primordial.

Combat
Shardsouls charged into combat with suicidal ferocity, showing no heed to their own safety. They would focus their attacks on one target at a time, shredding it with their claws. All the while, the madness exuded by the shardsoul would cause their target's allies to turn on each other when they tried to save their comrade.

History
Shardsouls first appeared in Faerûn during the 15 century DR after Telos fell to Vaasa during the Spellplague. As of 1480 DR, they were created from the body of Telos using secret rituals by the Luminaries of Telos City.

Rumors & Legends
It was suggested that the derro may have created similar mad constructs even before the arrival of Telos on Toril by forcibly splitting the spirit of an earth elemental into three pieces and trapping each derranged piece in a metal body.
