The agent of the arena
This quest will be offered to you by a 'Shady looking Cornac man' in the north section of Derth. Choosing to fight in the arena will pit you against three foes (a Slinger, a Gladiator, and an Arcane Blade). Defeating all of them will unlock the Arena Campaign, as well as granting two bonus Generic Points as a reward.
You will have the option of giving this reward to a party member that satisfies the following conditions:
- It is not dead, and it is on the current map
- It may be fully controlled by you
- It is not a summoned creature with a time limit
More specifically, Alchemist golems, Worm That Walks, and Mecharachnid pets are allowed to receive this reward.
The shady Cornac will only spawn if you first enter Derth before you reach level 14, when Storming the city begins. If you are going to do the arena quest, you first enter Derth before then. Additionally, he can be killed by the air elementals that appear, so it is recommended to do the arena quest before then.
