Clarification of keystone

Hi

Haven't posted before so unsure if this is the right section to ask (I'll ask there if anyone can point me in the right direction) but can you clarify how the new keystone that states "All possible League Map Crafting Options are Available while six Gateways are Allocated" functions in regards to mechanics have variable costs/sizes, for example , essence costs 2 chaos orbs some leagues and 3 on others, will there be 2 essence crafts on the Kirac mod list or one? Is it chosen at random? Will the more unique crafts like rampage and such be on this crafting mod list too? Thanks in advance for anyone who can help clear this up for me

Might be wrong but the way I understand this is:

Usually you need to complete x maps to unlock Kiracs map device crafts but now you can ignore those unlocks, if you have at least 6 gateways allocated.

This is going to require quite a bit maps completion anyways, so realisticly its only interesting if you wanted to unlock the most expensive map device crafts early and thats about it.

It means all map crafting options, even the ones not on Kirac's crafting bench this league like Blight.

I was hoping it includes stuff not on the map device normally, In the announcement page for the league in the keystone part it does say "With the right keystones allocated, you can craft Vaal Side areas, become possessed by a Tormented Spirit, place a single gigantic explosive charge in Expedition, or play any Kirac mod regardless of what he offers you." so the final part of that sentence led me to believe that the keystone would offer things not available for the league without the keystone
