Vessel of Ymir

The scream.

The Vessel Of Ymir is an unobtainable staff only titan. This means that only staff are allowed to use it. It takes the form of a compressed version of Ymir's Founding Titan. It is the strongest of all titan shifters aside from its True Form, permenantly increasing in strength with each roar based on the titan it fights, and having the highest base M1 damage.
