So I've made this mob arena on SB, the mob arena consists of a dome which the players start in the middle. There are multiple areas which the players can explore off to making it seem pretty interesting, there is a lack of grass in order to let the players hit the mobs which are smaller than 1 block. Then another feature is that there are platforms for archers to use, making the class actually viable. People can check out this via doing /is warp MarbleBlue. I'll attach some screenshots below if you wanna just see it right now. I also forgot to add that I have created a wave txt file which I will give to the head admins or owner if they want this arena added.
Should have asked someone with fly to hover over it and get screenshots . Overall, I've seen it and I think it's good. It'd be a good addition just to give more variety in mob arena.
