This Tech might make Lunar Lancer the fastest farmer and if not, a pretty fun character to mess around.
This tech is Grapple Cancelling. which you'll need a good amount of flasks, i recommend bandolier. Some healthy amount of jumps. and the most important of all, chronomatic emblem which i'll explain why.

You use your Ability to grapple somewhere. when it starts pulling you forward, use your flask. this will cancel the grapple animation, so you'll be able to have some turning control, while maintaining the speed. And thanks to the Chronomatic Emblem, your grappling hook will be completely refreshed, and you can do it again to keep going as fast as you can or to pivot your direction to steer around your incredible speed. The only down side is that it uses your flasks, which might harm your peformance if you rely on it, the tech is a bit hard, but nothing impossible. It is hella fun to do it, i recommend trying even if you don't plan on using lunar lancer just because how fun it is.

Lunar Form Cancelling or Moon Power Saving.
very simple, just press Tab or your build mode button, mid lunar form, you'll return to base form while saving a bit of moon power. It can be useful on delve since it doesn't send you into a loadnig screen whenever you go deeper, other than that it is pretty situational.
this also serves as a warning too, it can accidentally happen so whenever you use lunar form, be aware to not cancel when you didn't want to.

Das it, go fling around in the speed of light
