From Alathra Wiki

WoahBaptism is a canon sword used in ceremony's to introduce new members into WoahBradism (a religion formed around a 'god' named WoahBrad)

This sword is strictly used just for these ceremony's and using it for anything else is punishable by death. Though this sword is seemingly not special, unbeknownst to the average player, it was kissed by THE WoahBrad, THE WOAHBRAD #OMG!!!!!

That is all (also it was the first sword to kill Brad so it has a connection to him, Brad needs blood.. BLOOD FOR BRAD!).
