So I'm releasing some medieval mode weapons for us to try out. They will cost a bit more shillings than normal "weapons of the day" but they will be around for much longer and some might stay. These weapons are intended for medieval mode, and while you can use them outside of it, discussion of balance should be in relation to MM.

The Medieval Project was a pack of Weapons of the Day focused on Medieval Mode released mid June 2012.
Originally, all the weapons were done by girl, but some days after CHAWLZ released a few weapons to add.
