What I am suggesting is a team vs team race.

There would be one floor before the boss that would be based off the jelly farm level (with a variety of monsters that would be different for each boss).

This would be a timed race with points being given for % of Crowns and materials collected as well as % of monsters killed. (thus a team that rushes through would not necessarily score higher)(there are no minerals as their sizes are random)(CR and materials on your screen would be able to be picked up by another team member)

Penalties happen for each time any team member dies and if the CR and material pickup is less than 70%. Points are taken from the slower team based upon how many seconds they were slower (but if they collect more CR then they have a chance at winning). (to prevent griefers from stalling out the winning team the game would end 90 seconds after the first team to finish wins)

The bosses would be chosen based upon the LD tier with all "bosses" (battlepod, razwog, ironwood sentinel) up to the Collector for tier 1, all bosses after the collector up to the roarmulus for tier 2, and all danger mission bosses as well as vanaduke for tier 3.

Each team would face the same number of monsters and boss as well as the same pre-boss level so that no team would get an "easy level".

Much like the 3 levels that acquaint you with the battle sprites there would be a party button right out the starting gate, this party button would only start the timer after everyone gets on.

To the victors go 3/4 of both groups collected CR and materials (mats distributed randomly by stars with winners more likely to get the better ones) as well as 5 Krogmo coins.

To join this PVP would take 250 CR. (Players are allowed to choose between Guild teams and random teams)
(Custom made teams from friends and guildmates as well as invites costs 300 cr per player)
