True. It would be a little OP if the bow haved a high fire rate. And the ammo idea, i think its also good, because then you would rationate your ammo for needful occasions, like a zombie hulk if you aren’t melee related.
-Then the hunger idea, also sounds good but it would be a little pain to haul around, if it makes you hungier all the time you carry it with you.
-And the hp recharge method sounds nice to me because, you could use it when you really need it instead of all the time, and make sure you don’t get hurt too much so you can use it but if you use too much it won’t be beneficial, because the longer you rely on it the frailer you are. Hmm sound pretty good.
-Lastly, i also thought of a sun-based bow too but i’m not sure. xP
