Upgrade Sequences

• Advice:

Although plagued by low balance, with the right upgrades, the Bipennis can have a critical rate higher than any sword. One of the better blunt weapons for Humans/elves, It can be made in a similar way to the Mace with no crit and high max, although it sacrifices balance for higher minimum damage; or one can focus on its crit and make a weapon ideal for knocking the mask off Siren.
