I not being able to progress the atlas feeling like quiting

I have the chance of 100% dropping 1 tier higher maps, but i still cant sustain maps wtf i literally cleared 13 tier 10 maps and they all dropped tier 9 8 7 and just like 5% of tier 10 and 11 honestly that makes me wanna quit if i dont find a solution i just hope im just being dumb, right now i have 0 tier 10 and 1 tier 11

Are you alching your maps? I'm doing alch&go on my maps and getting up to reds just fine. I'm not doing anything special either, no super juicing strategy or whatever. Hell, my problem is actually surviving in T14 maps more than it is sustaining them.

Since you're on trade league, consider buying maps and also use horizon orbs and Kirac missions to fill out the rest. Kirac missions would also refresh his inventory, allowing you to buy more maps that you need.

It gets a lot easier to sustain once you unlock more atlas passives and have 2 voidstones.

100% 1 tier higher from atlas tree, and 2 voidstones socketed your experience is baffling.

You are already there, get the 1 point 3% chance of kirac mission+two kirac missions per day. Checking his mission for uncompleted maps, and checking inventory on refresh are a big deal if you don't want to buy maps from players.

You shouldn't need to chisel or vaal to maintain T11 maps, something odd is occurring.

Are the voidstones making maps on your atlas have no completed T10/T11 maps? From your post it doesn't sound like it, but that can brick your sustain.

This league I got all 100 from kirac or drops, only the last 2-3 I had to plan. I spent a lot of alcs on maps from kirac, never spent chaos. But buying a handful to speed atlas progression isn't a bad idea.

You get up to 20% chance to drop an adjacent map, if you're struggling put some planning into benefiting from that.

Don't think he has voidstones if he's only up to T10 maps. Unless he went and bought a carry for them.
