Back to Basics Scarab/Map Farm

Curious if anyone has an atlas tree, i've been seeing a lot of mixed info on how to build one with conflicting answers with stuff like if "tier 1-15 maps have x% chance to drop 1 tier higher" help or not

Personally I tried B2B and didn't find great success with it. Ended up just doing some things I like + blue altars.
Poe planner has a tool to play around with atlas tree.

Also, definitely take the +% chance for map to drop tier higher nodes. They do make map drops better.

The issue with B2B is that it swings very hard. You can go 10-15 maps getting nothing with low rolled B2B-percentage and suddenly have the god tier map.

T16s have plenty of alternatives that work better imho since you can add other things that aren't really doable in T17s while T17s benefit from B2B a lot.

% for +map tier is also very important for T16s as it increases map sustain and overall T17 drops.
