How do I get Boss Atlas points?

did T15 boss = 2 points
did T15 irradiated = 2 points

now I am at 4/10 and I know I can do a T16 irradiated map next which leaves me at 6/10 points. So how do I get the remaining points? Google doesn't know, Reddit doesn't know and no streamer shares their secret on how they got 10/10 points.

In the previous league we had +1 map level due to corruption but this is no longer the case.

Corrupted/Cleansed areas still provide +1, but as a rare innate modifier;

- LvL 79 T15 boss (T15 map)
- LvL 80 T16 boss (Irradiated + T15 map)
- LvL 81 T17 boss (Irradiated + T15 map + innate +1 Area Level Modifier)
- LvL 82 T18 boss (Irradiated + T16 map + innate +1 Area Level Modifier)
- Arbiter of Ash

thanks a lot! The +1 Area Level Modifier seems to be a rare mod in a cleansed map.

fwiw that modifier can show up on both corrupted and cleansed areas so check the corrupted zones before cleansing if you still need these points
