Well... this guide opens with "Please don't be a R15 Calad / R0 Sakpata DRK..."
I have been exactly this for about two years now, and only because I have focused more so on Sortie and other content than Odyssey (I also took a year break). It baffles me how being a R15 Calad / R0 Sakpata DRK is a bad thing.
I had a look at the guide, and while I admire how plentiful they are, some of the sets are puzzling. You're right about random Geas Fete equipment which has no place in 2024, especially if a player has a full set of R0 Sakpata. It is old gear severely lacking in defensive stats. I've had a better time making my own sets from the damage calculator, and it feels like I should share some of those soon.
WAY too many "guides" show you what the best sets are assuming you have Nyame/Sakpata maxed, which is absolutely ridiculous for anyone looking for a guide. Nobody with gear this maxed should be needing help from anyone else (although a few might). Would anyone be interested in my sets from the damage calculator? I'd only take the time to share if there is decent interest for DRK sets.
Sakpata doesn't matter if it's R0 or R30. There is sick stuff on the augments, like the hands getting STP, but the main reason to use Sakpata is for the massive MEVA and the DT. If you play Ody and Sortie, you need to survive, using Sakpata is better than any glass cannon busllhit. It's still great DPS pieces even at R0, it's not gonna beat your Relic legs, but you also won't die as much in them.
As for Nyame, yeah, the WSD is on the augments, so if it's sub R25, you still need to use the AF, Relic and Empy pieces with 10%/12% WSD instead, and fill in your weaker Nyame in the other slots. If you are literally R0, you may have to build some Reisenjima gear with WSD rolls on them, but none of this invalidates or makes guides useless, you just don't know how to *** read them...
If you don't have said piece, look at why that piece is good and find a suitable replacement for it with similar stats. Or, crazy idea, go try to build/earn/buy it. Guides are to be used as a base, and then you build around them until you can get the gear. The WSD Calculator is great and you can use that to help you, but it's also VERY BAD if you use it wrong. If you enter the wrong buffs or the wrong mob stats, you are going to get recommended really shitty gear choices. It will bring your acc/atk up to cap if you gave the mob too much eva/def, and put on shitty acc/atk gear that you didn't actually need in-game instead of WSD or PDL stuff that would be ideal for that mob and so on.
If you can't even use a guide properly online, I wouldn't trust you with a WSD Calculator at all.

Unrelated side tip, find an Ody group and build other REMAs. If you aren't gonna make Foenaria, make an Anguta or Mythic. You need a scythe and using only Calad isn't gonna work, especially in Sortie. It may not be easy to find a group, but this is a team-based game and you aren't gonna get any of the good gear without one. Idk how you have spent 2 years in the game without finding an Ody group and at least doing V5 or V10's. The game is, imo, not worth playing without a group. By all means, do what you want to do, you just sound ridiculous when you complain about guides not being catered to a R0, one-weapon DRK that is too lazy to get the gear you need.
