Each Monolith Timeline has a fixed pool if avaialble Modifiers and Areas/Enemy Types.
I would not consider any of the timelines harder or easier though, because this is heavily build dependent.
The most noteably difference is that Spirits Of Fire has dodge and mark for death and deadly if not damaged recently as available modifers, which are not present in Age Of Winter, but Age Of Winter has Endurance as moidifer.
Deadly if not damaged recently however is a very easy modifer for alot of builds that have very good and fast damage projection.
Spirits of Fire does have Siege Golems and Ospirix Lightmages, which are considered to be some of the harder mob types, but that’s build dependant again.
Now on a more general note: I honestly don’t understand people complaining about empowered farming being to grindy.
This is an endgame activiy, this needs to have some long term goals. None of the blessings is actually build enabling, so there is not reason that you have to get those blessings.
They even reduced the normal timeliens even more with this patch, but roleld back a bit on the empowered ones, that’s perfect IMO.
The first one or two runs are roughly as long as the old 081 MoF in the empowered timelines, but after that the new system is faster.
We actually don’t have a major difference between 081 and current 082H in terms of echoe count.
And with the new system the player has so much control over the difficulty and there are so many strategies and nouances available.
All i can say to anybody that complains: Get used to the new system more, learn it, master it and you will discover that the new system is better, easier and faster if you utilize all tools available, while still offering the possibilty for extremely difficult high end content if you build can handle it.
The new system is so much more than brainless grinding that we had in 081.
You have so much control over the echo web and there is so much different thigns you can do.
