The slime slayers are working together with the artificers and Elminster Aumar to create the ultimate weapon. Their base for this weapon seems to be Slime Slayer Sigurd “Sliggy” Sigurdsson

The weapon includes an eyepatch, an arm, a bow and some boots.

Slim slayers sight
This eyepatch allows sigurd to detect slimes from an immense range. While attuned to it he is also able to use the eye he lost due to drow poison.

The arm
The arm is currenlty unusable as a weapon. Sigurds arm has no bones in it and has several enchantments on it making it unable to be fixed. Until the arm is fixed this robotic brace allows Sigurd to use the arm, but not utilize its power.

The boots
Currently being worked on by Azid and Dargeir. its currently unusable but is seemingly able to let Sigurd Misty step.

The bow
The bow was not made by the Slime slayers but rather found. Its currently unusable as it needs to be coupled with the silver arrow from the vault, Dodona the arrow. Until then the bow is useless.
