Aloalo Island All Paths - FFXIV Variant Dungeon Guide 

It's not that bad when you looking for it. The most difficult one to figure out are the alt path in the center and the secret ending. For the alt the sigil is very obvious so it likely triggers something, and the most obvious answer is that it has something to do with the mobs since the treant starts on it For the secret path it is spelled out in the lore tidbits you get for doing the paths as it tells you what the rituals are.

you underestimate dedicated gamers. look up Dark souls 1 DLC

@@boundesumo My personal favorite example if pokemon. I still to this day don't know how anyone figured out how to evolve Inkay.

It's extremely simple. Each path usually forces you to do an option, and the other option is another ending. The "puzzles" are figured out by the journal entries directly telling you what to do.
