First, although this is not technically necessary, clear all the wandering klakdyne eliminator DCCCs - they are not part of the ring event but they will get in the way if left up.
For the ring event, first clear all the standing groups of klakdyne eliminator DCCCs and mechnamagica battlers
This will cause two things - one is a bunch of activated clockwork workers to spawn on the upper floor and run down to the ground floor. The other is that mechnamagica hunter-seekers will start spawning incredibly fast. They also have very wide agro radii. A switch at ( -232, -13, -167 ) Copy/waypoint -232, -13, -167 can be turned to stop the hunter-seekers from spawning. Clear the activated clockwork workers to advance the ring event.
Once the clockwork workers are down, The Mechnomancer and four klakdyne eliminator Ms spawn on the second floor and run down to the first.
