Anabaseios: The Twelfth Circle (Savage) Part 1

Party at the south at max melee, tanks in the center of the hitbox.

After Engravement of Souls, check whether the 2 tower supports received Astralbright Soul or Umbralbright Soul, as this will determine which angel tether is responsible for soaking towers, and as a consequence which side of the arena the towers should be placed on.

DPS players should always position themselves on the middle platform opposite their tether angel. There will be 2 DPS players per platform; to avoid clipping the players on the opposite platform, the players tethered to the angels closest to the middle of the arena should keep their tether straight, while the outer tethers should cross their tether with the straight tethers. Avoid pointing a tether into a tower.

Support players will all be on different platforms. The Enchained Soul player will be on the southernmost platform, the X-marked Soul player on the northernmost platform, and the two remaining players can use whatever priority system they wish to decide which of the two will be on the inner west platform and who on the inner east platform.

All supports first soak the tower on their platform. Then, the Enchained Soul player moves to the outermost corner of their platform to place their AoEs and the X-marked Soul player moves to the outer middle corner of their platform. They move out of their AoEs after they've placed them. Their job is then done; as the yellow crystal angel is on the same platform as they are, they are guaranteed to be close enough to bait one set of White Flame beams.

The inner support players, after soaking their tower, will need to check which side needs the towers (if you have the same coloured debuff as the DPS players on your platform, the other side needs your tower). If you're already on the right side, simply drop your tower anywhere in the center of the platform while being careful not to drop it on top of the DPS players. If you're on the wrong side, place your tower on the innermost corner of the platform, so that the edge of your tower clips into the other platform and is accessible from there.

After this, the 2 DPS players who are responsible for towers each take a tower. You can use a priority system based on which angel they were tethered to to determine who takes which tower (for instance, straight tether takes inner tower, crossed tether takes outer tower is common on EU). The other 2 DPS players are instead responsible for baiting the second set of beams from the two yellow crystal angels. While positioning yourself for tethers, take note of which yellow crystal angel you're closest to, then (after your beam resolves) get as close to that angel as possible without falling off the platform.

Party at the south at max melee, tanks in the center of the hitbox.

Start at whichever chain source has the blue chain attached to it, then go to whichever chain source has the orange/purple chain attached to it. However, don't get into position to resolve those chains yet. Instead, wait at max melee until the boss has cast Parthenos, then quickly move into position for the cones. While this is happening, look to the north or south of the arena to identify where the angels will cleave.

After the cones, quickly move out of the subsequent Ray of Light cleaves, then go to whichever chain source has another purple or orange chain attached to it. This will always be a chariot, so stay out while moving into your spreads or partner stacks.

Finally, identify which platform is not being erased and quickly make your way there.
