Post all the resources you use in this thread. The thread may be used to explain various advanced gameplay mechanics, if you want to put aside some time to do a write-up. Keep discussions to minimum.
Moonrunes resources:
Official site - your first source of information. Usually updates at 6PM JST.
Official twitter - your second source of information. Check it if you're having problems accessing the game server and you're not sure if there's maintenance coming.
kon - visual guide maker for events, new story chapters, etc.
Humanity - IRL events' info provider.
Kazemai - Servant datamine with nice UI. Loads slowly nowadays.
Atwiki - Servant datamine, usually the first ones to get the data.
Material simulator - site for checking your Servants' mats needs. Has English UI.
Appmedia - various information.
Farming spots - self-explanatory.
English resources
Kyte's blog - your first stop if you want to delve deep into FGO gameplay mechanics. It's referenced by pretty much any other English resource you might be using.
FGO reddit - probably the largest hub for FGO activity for English speakers. Tons of megathreads, easily the fastest at getting both news and false rumors. After /fgog/, that is.
FGOGuide subreddit - more reliable than FGO reddit thanks to submissions being restricted.
Arts and Quick 3 Turn Diagrams - farming comps.
Command Chain calculator - calculator to quickly check damage/NP gain/stargen.
Youtube Content Creators:
Chaldea Radio Plus - official radio, releases weekly.
ka ga - provides various setups for farming.
Somen - if Somen hasn't cleared something with solo Gramps, then it probably cannot be solo'd by KH.
Kery Games - farming setups.
小黒唯 - bullied Kirsch
xNaya - Battle animation demonstrations, story and event battles of notes, challenge quests, occasional memeteams, and good taste in Servants ;V (quite from IRUN)
bys Game ch - for animations, whole story chapters, my room lines and gacha rolls (Nikiri)
cometdance - bronze runs from London onwards.
All suggestions to better OP management are welcome. /fgog/ will not be linked because I treasure what remains of my sanity.
