The Arena of the One is a Quest in Divinity: Original Sin II. Upon entering the Arena of the One, you are finally close to ascension...to Divinity. Will you be able to reclaim your rightful place and ascend as a Divine?
- Reach the Wellspring.
- Kill your embodiment.
- Reach Malady's beacon.
After you talk to the Eternal Arbiter, you will be teleported to the Arena of the One, along with your former companions, now Sworn to the God-King. You are instructed to get to the end faster than the others, but obviously, your former companions will try to kill you and stop you from getting past. If Alexandar is still alive, he will be here as well, and turn on you. With a high Persuasion however he can be convinced to set aside his ambition to become Divine and support you instead. This will also award you the Favoured Son achievement. If that doesn't work the simplest solution here is to kill them all, but you will not be able to loot your former companions' bodies. You will be granted no XP for killing any of them as well, but since they are weak, it is best to finish them all then walk towards the end.
As you move forward though, there will be 2 Eternal Sentinels that will try to stop you. Defeat them both, and you will receive 27,900XP per kill. Move towards the Wellspring and a cutscene will play. Apparently, Dallis has followed you, calling you predictable. She will then use the Aetheran rod to destroy the Wellspring, purging it of any powers that lay within. Her actions have effectively ruined your grand plans for ascension, and left the arena in ruins. You are now tasked with escaping the arena before it is too late.
As you attempt to escape, however, the gods within you and your party will surface, angry at your failure and calling you their worst mistake. At this point, you are given the option to "give yourself" to your god, or refuse. If you choose to "give yourself", your god will rip out your source and your character will instantly die, but combat will still be initiated with the rest of your party members. If you refuse, they will angrily proclaim they made you, and combat will still begin anyway. In either case, you will have to fight your clones, so defeat them all for 55,800XP each. Once the last clone remains, a Source Titan will spawn from the last clone, and you will have to fight it. Defeating it grants an amazing 125,550XP (the 55,800XP is replaced with this amount). Don't forget to loot the Source Titan after it's dead for some really nice loot.
Note: Sometimes, there is a bug where you will not receive 55,800XP for killing a clone. If this happens, you will have to reload and kill them again or you will forfeit the XP.
After the fight, use Malady's beacon to escape. Be very careful not to step on the lava surfaces - they will instantly kill any member if stepped upon! Only one member needs to use the beacon, and a cutscene will play with Malady saving the entire party from certain death. After being rescued, you will be granted 69,750XP, although this XP reward is not shown in the combat log due to the transition into Act IV, wiping your log clean.
Back at the Lady Vengeance, you can spend a night with one of your companions. Once you're ready, talk to the figure statue to summon Malady, and you'll continue the journey to the final Act, Arx.
