Amarna spawns when you kill
some specific npcs, which are special and only visible during the mission*
- there is more than one special one
- the special one needs to be shot down to 50% then amarna appears
- you can spot them by their false affiliation related to their surrounding npcs (single ammon in a horus field f.e.)
- npc fields contain of this sequence:
- horus isis phyrus - repeat
- khons shysis ammon - repeat (might be ammon shysis idk)
- abasis odion ignomes - repeat
- the count can vary, 1 rarely, mostly 4, sometimes 6 etc...
Soris gets spawned by shooting 5 npcs with red alloy, they are placed randomly on the planet.
When they got shot down to 50%, they freeze for some seconds and then you can move them to the rally point, when all 5 red ancients reach it the soris will spawn. You can/shoult not kill the red ones until they reach the rally point.
Giza can be spawned by killing npcs and collect their dropped intel (~3% per intel)
* For all bosses you need to accept the mission in r5 orbit, sirius ship required.
Also, next amarna can be spawned 15 minutes after it is killed, soris as well. Giza can be spawned 12 minutes after it has been spawned, so you can spawn multiple gizas without killing them first
