Should i spend my farm mats on this CE? If yes, then which servants should i use with this CE?
Nope not really unless if you have people like herc or cu whom you want to survive more or people who increases their damage with the lower health they have like the Archer and Rider Anne and Mary and Hijikata.
I just farm them though since I want to MLB all event free CEs.
If you want to and could reliably farm oil and cement easily I suggest skipping.
Yes you should. You need it to make farming easier.
Get the 5 copies and put each one on a servant when you go farming for maximized gains.
The art itself is enough for me to MLB it, tbh. Ironically, it fits Nightingale herself pretty much (and other fragile Bsks too). And if you want to clear out the oil and cement items in the shop, you should really purchase all of the CEs asap.
Yes. You should. It is as they say, you need that to farm cement and oil one go though it drops well on the quests. Already have 7 of it. Including the ones on the shop.
