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.

Preparations

 * Frozen Soil - makes the battle much faster since it prevents the Convicted Criminals from using Resurrection Signet.
 * Various nukes/AoEs - the battle is fought in a small area and foes will usually be close together.
 * Any other high DPS build will do for this battle.
 * A Minion Master is not as effective here since creating minions takes time and will slow the process of faction farming.
