The Doomtar is a weapon found in the Progressiverooms.
It is a merge of a guitar and a rather 'dooming' axe. The based and everything is black, with a little red symbol underneath the fretboard, and the lower base is shaped to match the head of an axe. On either side are the glass-resembling head of the doomtar, which are rather really hot and shouldn't be touched, or else you may suffer burns.
The item is quite powerful and can heat cut many things, but also can harm individuals or themself, for instance, if they accidentally burn themself via the blades.
Not to mention it is also moderately heavy.
