Idea how to utilise this device – it teleports 5 man party to small random location with one of the legendary mobs. That simple.
We gather party, grind a bit to build it and then we can battle boss for a reward.
Similar to Torchlight 2 phase portal with a twist. We get few locations and few bosses. Each location and boss have it’s own mechanic so adding them could produce interesting battlefield:
this first boss from gauntlet tier 1 (who is easy but have killer attack) can easily be defeated at open but in sewer with narrow corridors this fight could be completely something else > : )
It would be thrilling not knowing what will we get.
