the The secret of improving experience and loot on carnivor is doing a lure a chain, try chain. Try to be always hitting more mobs when a lure starting to die start to move to next one and keep shooting and lure more monsters, another monsters. Another trick is get the loot only in next lap on the cave to dont so you don't lose time going back to loot( this option is only valid if only you are hunting in the cave and pep people wont grab your loot while you rotate the rest of respw, also i recomend respawn. Also, I recommend you to go to -1 only if you kill the respw respawn of -2 really fast and anyway dont don't grab entire -1 respw if dont respawn if you don't need to just to. Just do the lures to make spawn time on -2.
