It is true that there is a way of avoiding this, as five parts of the sequence always ends in the exact same spots. If slice number one is located directly behind Argos Lost Ark Gold, then it will end on both the first (back of boss 11 o'clock position) and the fifth (front of the boss, five clock the position) tiles, whereas it will end on both three (side that of the boss one o'clock position) or seventh (the other part of the boss seven clock place) tiles.
Argos features a one-shot mechanism that requires everyone to be in a safe spot. In this portion, the sun's safe spots as well as the moon's safe zones will spawn and total 8 (the moon safe zones tend to be close than Argos as opposed to sun safe spots).
Each affix will be spawned in every direction from the direction the boss is heading. It is crucial the only person in each safe spot (for the appropriate affixes obviously) If you have more than one in your secure area, only one will be able to withstand the shockwave Argos releases.
So, to avoid that ahead of starting phase one, a member of the group will likely be saying "1234," followed by "NESW," or just the latter. This means that the first party member goes North while the second member heads east, the third party member moves south and the fourth member heads west.
This applies to both parties, as each party's members are classified by numbers one to four. Although safe zones will not always be exactly to the north, east or south of Argos and Argos, they are spawned within these general directions therefore Cheap Lost Ark Gold, if you're assigned west, as an example at this point, locate your safest place on the western side of your boss.
