I usually change up my weapons a lot. But for the most part, it's like this:
Normal: Cutlass, Broadsword, Grenades, Doll
PvP: Cutlass, Broadsword (for those people who have no aim what so ever..
), Grenades (for killing myself if invisible), then any 4th weapon I wish to use.
Invasion: Broadsword, Staff, Grenades, Doll.
