In Path of Exile, if you just don’t understand how people progress so fast through the atlas in the early days of a league since when you are the person with the most progress in the atlas you don’t have any maps to buy, because no one is able to run the maps you would need. Do you want to know did people reach T16 maps/Shaper on Day 2 of the League?
Get 6 man party. Rush through acts, farm aqueduct for tabula, so you have dps to clear maps. Kill kitava 12 hours after start. Do zana quest. Do her dailys. Daily and level up refresh maps, she sell.
Buy maps from her (x6 peoples, x3 – 4 due level – ups). Now you have pretty much all low maps. Unlock those maps, everyone in group have 40+ atlas with most white maps unlocked. Now mapping, building map pool. Sell maps you dont need, buy maps you need.
Buy unique maps and complete them. Caer Blaidd is t7 and have 4 guaranteed maps drop, Hallowed Ground have 3 maps drop. Do atziri – apex of sacrifice drop lots of low maps (like 5+ whites per clear), atziri drops sell for lot early (first day).
If you’re not SSF, it would probably be faster to do the chaos recipe 4 time and then buy the Tabula than to farm it. At least while making the chaos recipe you’re advancing the new content and will be near the end sooner. That is, if you’re doing that past the 1 week mark. If it’s still the first days of a league, farm away!
It’s pretty hood xp until you are out more than 1 – 2 levels of the safety band. The formula used to be 3 + player level/16. so around 10 levels, which is only like 73. At that point you should consider moving to Ossuary/Reliquary if you are slow poking, which can get you till 78 or so.
At level 80 safety band is 8, with a delta of 9 giving you more than 95% XP. 81 is still somewhat doable pre Kitava, but 82 would really really drag. Hopefully the above guide will be helpful to you.
