you should fix the damage on flamarang. its incredibly weak (even weaker than the trimarang)

You should make the Possessed hatchet afflict a wound style debuff that gives bonus damage if you hit the same spot again. Or if that's a bit much then just summon a friendly spirit to attack enemies for a few seconds. Like a summon, but it deals melee damage and is temporary. Afterall, the hatchet is posessed, why not give it a ghost.
