I was venturing in the desert, and didn't have anything good to stave off the heat yet. Found the tools for a vehicle, and added on a hydrant, so it would constantly spray Link with water.

I often make gliders to get around, but launching them is an issue with their high stony friction. So, I take out some pieces of meat, use an ice attack on them, and then (Don't pick them up! They're not Materials so you can't drop them) weld them onto the bottom of my vehicle. Now, it essentially has a slick ice block on the bottom and can launch pretty easily.

It's fun looking at the many giant mechs people make, but for practical Zonai combat, I've just made a simple autotank; using those homing tread things, with an electric horn on it. To increase its range and spread, I attached a random metal spear sideways onto its tip to make it harder for a monster to walk past it. The resulting creation is only about 9 zonaite, so I can actually make several of them for a fight.

My favorite invention is the 2 fan 1 stick hover bike as it is almost game breaking and only costs 9 zonite.

Put a large lightbloom seed on the front and it’s perfect for tooling around the basement too.

I made the "orbital laser drone" that I'm sure is nothing new for folks. For those who have not seen it, it works as follows:

Base: 1 Hover Stone with something else on it to add a bit of weight. I just use a second hover stone.

Weapons: 2 Construct Heads attached to the left and right sides of the Hover Stone. To each of these Construct Heads, attach as many Beam Emitters as you can get away with. I put 7 on each side for a total of 14.

Lift: Attach 1 rocket to the rear of the base at a 45° angle, to shoot the satellite up and forwards at whatever it is you want to kill.

It's very effective at killing big enemies like Gleeoks, provided you can evade their attacks for a minute or so. If the drone dies before the enemy does, just time reverse it back in place and let it get back to work.

Problems I have encountered: As enemies like Gleeoks may occasionally take to the air, they can bump the satellite and send it drifting out of range, despawning it. Can be mitigated by attaching a dragon scale, but that adds extra work. The drone is also very expensive to entirely autobuild, using up over 100 Zonaite. I haven't found a more effective means of obtaining large quantities of Zonaite other than by slowly collecting it manually in the depths, so the drone is currently used sparingly.

Other than that, the 9 Zonaite budget hoverbike is my only other saved favorite schematic. It took a bit of tweaking the fan/steering stick placement just so, but I managed to get one that flies perfectly straight and handles really well. I just lament the fact that I fully explored the depths before learning about that invention, which would have made navigation so much easier. But it really sped up a lot of the later overworld/sky island exploration I did, though, and makes delivering objects/crystals/Koroks over long distances a breeze.
