I set up the server I'm on now with finishing the cave in mind. Wouldn't have happened without the upgrade station mod. 3 of us on level 330ish rexes with 200 armor saddles, 3 dire wolfs over 300 and assult rifles with 755% damage lol Took over 4500 rounds and we lost all but one rex. I think one of my mates had a 600% compound bow too and used over a 100 arrows when she ran out of bullets. It was ridiculous. On a vanilla server, you'd need at least a tribe of 10.
