Rimetooth

Weapon (spear), artifact (requires attunement)

During the Confluence, when the Shadowfell Gate, known as the Shedimneer, opened and the northern Dwarven kingdom and the entirety of what would become Makain were threatened, the northern tribes rallied. In an unprecedented display of unity, they gathered behind a single leader, Asger Wraithbane.

They united behind Wraithbane not simply because he was a capable leader, but because he bore the mighty spear Rimetooth. The shaft of the spear was made from the legbone of a large Remorhaz, and the spear-tip was a large, crystalline canine, serrated on its inner edge, given freely by Makai, God of Wolves.

After the Confluence War had ended, Wraithbane founded Makain, a confederation of the tribes in the north. Rimetooth was passed to his son, and then to his son’s son, but anyone with the skill to defeat the current bearer in single combat, and the endurance to wield the spear, would be named High Chief of Makain.

Magic Weapon. Rimetooth is a magic weapon that grants a +3 bonus to attack and damage rolls made with it. The spear also functions as Boots of the Winterlands, and a Frostbrand. When you kill a creature using Rimetooth, its body turns to ice. While you are attuned to Rimetooth, your skin is cold to the touch, and your breath mists in the air, regardless of surrounding temperature.

Blessings of Makai. While attuned to Rimetooth, you gain the following benefits:

You have advantage on Wisdom (Perception) checks that rely on hearing or smell.

You have advantage on an attack roll against a creature if at least one of your allies is within 5 feet of the creature and the ally isn't incapacitated.

Your movement speed is increased by 10 feet.

Investiture of Ice. If you are holding the spear, you can use your action to cast the investiture of ice spell from it. The effect lasts for ten minutes or until you dismiss it as an action, it does not require concentration. You can't use this property again until an hour has passed.

Call of the Alpha. While you are holding the spear, you can use your action to attempt to summon aspects of Makai's demigod sons, as with the conjure celestial spell, but does not require concentration. When you use this property, roll a D20. On a roll of 1-9, you summon an aspect of Sköll. On a roll of 10-18, you summon an aspect of Hati. On a roll of 19-20, you summon both. You can't use this feature again until the next dawn.

Tundra's Toll. When you become attuned to Rimetooth, you suffer 5d10 cold damage. While attuned to Rimetooth, you deal 1d6 cold damage to any plant you touch that isn't a creature.

Destroying the Spear. In order to

destroy Rimetooth, Makai's tooth

must be severed from the shaft

by a +3 magic weapon that

does slashing damage. If a

creature is attuned to

Rimetooth, the speartip

will attempt to fly back to

the shaft at the end of the

attuned creature's turns,

as long as they are within

30 feet of one another. If the

speartip is being held, the

creature holding it must make

a Strength check (DC 14) to

hold it back. Once it is

removed, the tooth must be

returned to the mouth of

Makai. Once the tooth has

been returned to the god's

maw, the spear is

permanently destroyed.
