Borderlands – How to reset the badass rank bonus stats

Moonstones and Money pickups are shared with all players in co-op. As for ammo, when you pick up ammo of a type you're full on, it will be transferred to another person, except for rocket ammo and grenades, which cannot be picked up if you're full on them. Everything else is per-player.

Legendaries appear in the vendor at a much higher rate than BL2 - I got three at Level 15 alone. Legendary drops from random enemies are probably as low as they were in BL2...like way low. IF you know what boss drops the one you are looking for AND that boss respawns (many in the TPS do not), then you can farm him/her/it. I wouldn't waste money trying for getting a legendary from the slots -- again, very low odds it they are same as BL2 -- use that money to buy one from a vendor when it appears. It will.
