Spreadsheets
PSO2 Modding Discord
A discord server for discussing Phantasy Star Online 2 modding. Also open to discussing modding for other Phantasy Star games here. It's not the largest group and we'd like to be welcoming.
PSO2 Downloadable Sheets
A set of downloadable sheets generated by Aqua Model Tool that in theory list every possible character piece as well as lobby actions, mags, pets, classic photon blasts, dark blasts, vehicles, enemies, and weapons. There's also pixel data for classic pso2 color palettes. Separate sets are generated for JP and Global/NA clients. These may be more up to date in the Discord at times.

PSO2 Extracted Ice File Lists
Text lists of the contents of every ICE file in the game except the 3 probably unused v3 ones (older extractors showed them to just contain dated icon textures). Also notes the file formats for every non ICE file in the game's data folder. Useful for hunting down things, particularly since most pso2 filenames are based on English.
The PS4 file lists aren't up to date, and can't be due to how PS4 file extraction works right now, however the names in these are unscrambled. This makes it not only easier to guess what things are, but how to guess other filenames as well.

NGS Bestiary
A compilation of local game data and calculations to describe stats and gimmicks of the various NGS enemies.
PSO2 File Directory and PSO2 High Risk file sheets by Key A/Arredoval
A spreadsheet set containing a number of classic pso2 items. These contain a large number of important file locations, many of which aren't reflected in newer sheet attempts. Most of it was made well before the usage of the PS4 version for automation and so there are many pleasant, human touches in the listings that the later sheets can't offer.
Particularly useful for classic pso2 area file and id info.
PSO2 File Directory v3.0 Release by Frey
A spreadsheet set containing a number of classic pso2 items. It should be considered lower priority than other lists due to its accuracy, but has some things that others don't.
