Are there any good ways to find the cobalt and diamond pickaxe blueprints? I've been toughing it out in the magma zone with Griddle and the Resonant Prong for an hour or two, but I've only been absolutely heartbroken and crushed by two chests containing the magmawalker and three gold ore. :(
If you're looking for them for completion purposes and already have high Dojo stats with Farfields gear, using Caelo with Resonant Prong will be easier.
If you're still progressing through the game, I'd recommend not prioritizing the Diamond Pickaxe blueprint since there are stronger pickaxes in Farfields.
Also, the Cobalt Pickaxe blueprint drops in Farfields, not in the Magma layer. Hope this helps!
