Aksis, Archon Prime

Aksis, Archon Prime is the leader of the Devil Splicers and the latest claimant to the title of Archon of the House of Devils. Aksis modified himself with SIVA extensively in pursuit of godhood, to the point where he was more machine than Fallen and had lost all need for Ether. He lurked in his Perfection Complex deep beneath the Cosmodrome while his Splicers gathered SIVA offerings for him as tribute. As of the SIVA Crisis, he is the most powerful Fallen to have ever existed, until a fireteam of Guardians assassinates him within his Perfection Complex.

Gameplay
Aksis is the final boss of the raid, and as such, he has been tuned to be the most difficult encounter yet. His boss fight has two phases. In phase one, his upper body will be hanging from the ceiling and will be completely immune to all Guardian attacks. He will create SIVA containment cores that, if not destroyed, will allow him to summon a critical density of SIVA, which will wipe the team. The only way to destroy these cores is by using SIVA Charges. To obtain a SIVA Charge will require a special strategy. Shock, Scorch, and Null Splicer Captains will spawn, one on the left, one in the bottom center, and one on the right. These must be killed in a timely manner so that their cannons will drop. You will need these cannons for when the Shock, Scorch, and Null Splicer Servitors show up; they can only be destroyed by using the cannon of their respective element, and they must be destroyed fast, before they reach a download plate, or Aksis will then wipe the team due to a critical SIVA density. Not only that, but these Servitors will drop the SIVA Charges that you need in order to damage the containment cores. This process repeats three times: the first time will have two cores, the second will have three, and the third will have seven. Once all these cores are damaged, Aksis will temporarily shut down and the room will go dark. You might think that the fight would be over, but remember, this is only phase one.

Phase two has a completely different structure. Aksis' upper body will detach from the ceiling and connect with his lower body, which has muliple spider-like legs, thus revealing his true form. He will stay in the center of the room and hammer you with suppressive fire from afar using his SIVA artillery cannon, which has two separate firing modes: a single-shot that creates a large SIVA Swarm upon detonation, or a barrage of multiple shots that have a large blast radius. While doing this, he will, again, remain fully immune to all attacks until three SIVA Charges are thrown at him, using the same strategy from phase one. Once this has happened, Aksis will teleport to another location, and one random Guardian will become "Empowered". The Guardian with this buff must run up to him and attack his vulnerable backside. This will momentarily stun him, thus beginning the damage phase. This damage phase will happen three times in a row before he teleports back to the center of the room to fill the room with a critical density of SIVA. Once this happens you must go to the back of the room where there will be four lit pillars. Your entire team must jump on the same pillar only due to the fact that when your team uses a pillar it will go dark and you cannot use it again. But if your entire team successfully gets to a pillar, you will survive the crisis and the phase will start again. Please note that when Aksis gets to about 5% health he will teleport to the center and he will start self-destruct mode in a last ditch effort to kill you. You need to shoot and kill him quickly before he wipes your team.

Heroic Mode Changes
The Heroic Mode version of Aksis remains largely unchanged, but it can throw teams off guard if they aren't paying attention. For phase one, the major change is that in addition to killing Splicers during the add phase, you also have to watch out for SIVA Turrets that appear on the ceiling. These turrets are capable of doing serious damage at a fast rate, but can be temporarily disabled for a moment before they reactivate, allowing the team to briefly avoid focusing on them. For phase two, the team needs to throw six SIVA Charges instead of three to start the damage phase. This will take a bit longer because there will be two each of Shock Servitors, Scorch Servitors, and Null Servitors. These Servitors, just like in normal mode, can only be destroyed by a Shock Cannon, Scorch Cannon, and Null Cannon respectively.
