Guide to Luxon Arena FFF

The Jade arena
Obtained from
 * Arena Master Portus in the Archipelagos

Reward
 * 2,000 XP
 * 400 Luxon Faction
 * 150 Gold

This is the fastest known Luxon FFF(Fast Faction Farming) and can be finished consistently under 3 minutes, achieving an estimated 8,000 Faction/Hour.

Getting there
From Breaker Hollow walk south along the west wall onto a small hill and then you should meet Arena Master Portus. There's a wandering group right in front of the hill entrance consisting of 1-2 Creeping Carp, Scuttle Fish and Irukandji you'll have to take care of, as well as a group of 3-4 Oni that appear a bit up the path.

Make use of 2 semi-runners

Party
BRING Frozen Soil, preferably two people have it in case the first spirit goes down.

Semi-runners
 * 2 warriors or 2 paragons or one of each should take a running skill like "Charge!" or "Fall Back!" and use the extra points and slots for damage dealing and maybe a litte support.

Nukers 2-3 nukers are needed

See these builds
 * Build:E/Me Echo Nuker
 * Build:N/Me SS Nuker
 * Build:E/any Searing Flames Elementalist
 * Build:E/any Savannah Heat Elementalist

Area Healers Spirit Ritualists do well here, but most healers will do just fine.

From the Build Build:Team - 55/SS you could use the SS as a base be sure to take out the extra visage.

MMs are very powerful here since you can build up a 9 minion army by the time the battle starts, but an alternative is to let the SS nuker bring Consume Corpse for energy management.

Since Frozen Soil is Active while in battle, many corpses would lie on the ground. It would be wise to bring an area resurrection skill like Light of Dwayna to resurrect all of them quickly.

Note
This is only a base, you could freely add information in this content, and please discuss matters of what to delete before deleting it.

Disclaimer
Because of the bad spawns, when onis come after you or when the groups are scattered and when healers are in a mob using healing area therefore this "fast faction farming" is not fast as you think and can take as long as 5 minutes for a competent group.
