Ice biom boss map

[Bovine Lion]

One of Ice biom maps that boss can spawn on has no cover (the one that's basically a doughnut) on true nightmare depending on the boss this is basically impossible I strongly suggest changing this as there really isn't anywhere to go with falling.

It's actually the best boss map in the ice biome, as the crab bosses can just jump off into the hole. If you really need a spot to hide, there's a little ledge right behind spawn where the bonus chest will spawn that's a good place to take a breather, and sometimes bait the bosses over.

you got three different rocks for cover on that map plus small ledges off the sides and in the inner ring. like stated above bosses jump to their death. not just the crabs, anything will go off the edge if you wait on a ledge.
ultimately that map is a free cheese pass if you absolutely need a break

yeah i agree with the other comments here, and that map doesnt need cover in my opinion becuase hammer knocks bosses off the map and if you have good in air control you shouldnt be getting hit that much anyway, way better of a map then the ice bowl with the pillars, double lightning crab ice skull on bowl is crazy rough on true nightmare.
