I have a few questions. What are the purple pillars for? I found one of those blue coconut shells which seem to be inprinted on one but discarding it and placing it on there doesnt do anything nor does using the item do anything.
Also the sand castle thingie, I've found spiral sand but the same story there. I wonder, have I found the wrong items? If not, then how do I use them?
How do I craft things? ( I found an emblem and found out this is how I craft, I didnt know what alchemy was)
Most of the purple pillars are hints to figure out what goes in the empty purple pillar east of Sablee, not too far from the beach.
You got it right for the sandcastle, but the hitbox for where to drop the sand is a bit wonky, that's something I need to fix. You have to drop it precisely on a part that's already built, the middle won't work. Sorry about that...
Now that you have the emblem you'll be able to craft, you just need to talk to Eveii, one room to the right of the big red crystal in Sablee. She has "alchemy" written over her head ^^
There's also a walkthrough here: https://www.patreon.com/posts/walkthrough-by-33962675
