If you able to just make it work and it's will tp as to the arena like in the normal map it's will be cool, be it's will be better if you will build you own arena's for the bosses like gonna be in the normal map. and start to work on the obelisks please.

it's will be really cool to see that on this map, and i'm sure you will do that at some point, i hope soon as possible... :)
