About[]

This island was used to host the Development Tournament, which was the last part of the 30F Workshop Battle. The island was divided into two sections, north and south, where the north side was used to settle the Mad Dog Vs FUG fight, while the south side would be used for the fight amongst the 8 remaining teams.
Summoning Wells can be used to travel to certain parts of the island as part of the summoning mechanic used in the development tournament. Guide Robots are stationed at key areas of the island in order to help regulars with the various rules and mechanics of the tournament.
