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.

Party
Bring Frozen Soil, preferably two people have it in case the first spirit goes down. This skill is essential to kill the spawns quickly.

2-3 nukers and AoE damage are recommended (Searing Flames, Spiteful Spirit, etc.), as the groups will usually spawn all bunched up.

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

MMs can be 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.

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 occasional bad spawns 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.
