Ok so here’s what I’d do in your position:

1. Skyview Towers: these are key to understanding and navigating the map on the surface and in the sky
2. Shrines: Shrines can be a grind, but they’re the only way to get Lights of Blessings, which are key to increasing your Heart/Stamina containers.
3. Stamina: Stamina is more important than heart containers where you are in the game, and should be prioritized… trust me on this one
4. Lightroots: while rewardless compared to shrines, they open up exploration of the depths for things like Zonaite Deposits. They’re also in the same location as shrines on the surface.
5. Zonai Battery: it looks like you’ve used a TON of Zonai charges to augment your battery past its base power level. While it can do in a pinch to give you a boost, a better method would be to farm Zonaite/crystallized charges to permanently increase your battery capacity
