Terragrim

The Terragrim is a short range, rapidly striking melee weapon, similar to the Arkhalis. It can be found in an enchanted sword shrine in the underground.

Trivia
The Terragrim's name is a reference to the Valmanway from the Castlevania series. Specifically, it references Castlevania: Symphony of the Night, where the Valmanway was instead known as the Crissaegrim. Like the Arkhalis, the Terragrim's function and appearance are also based off of the Valmanway.
