Is there an item/tech to prevent fall damage?

And if not, could we get one?

Some friends and I are working on structures that are rather tall [Anywhere from 300 blocks high to 800+], and with height like that...It's pretty damn hard to judge when you need to double jump. I remember there was the Bouncy effect which I believed negated fall damage, but it was removed and all. Is there something we should have to deal with this?

 

Air dash + this mod: http://community.playstarbound.com/resources/better-dash-no-more-double-tap.3919/
Air dash resets your vertical and horizontal speed. The mod allows you to use it easily.

Alternatively, you can spawn in armor which has the bouncy effect using spawn commands. There's also the option to get the gravity EPP augment, which reduces fall damage and makes you fall slower, you could use the spike sphere and attach to the side of the building every once in a while while falling (if your building has an uncomplicated outside with no ledges for you to hit, which would necessitate jumping away from the building), and there's always the option of looking for a spear with the rocket spear special, which works great in combination with the aforementioned gravity augment, since it allows you to glide for a limited amount of time using your energy bar, and if you have multi-jump (which is the better tech when compared to double jump anyway, especially for fall damage prevention), you can switch between the two and get a significantly longer period of use out of them before being incapable of moving back upwards since you can recharge your energy while jumping, which works even better if you have air dash, since you can use that an unlimited amount of times. Not only does this combo of gravity augment, air dash, multi-jump and rocket spear make fall damage easier to deal with, you can also move up a ledgeless building more quickly with it (you just have to make sure to activate your spike sphere while you still have energy if you can't reach the top in one go), move quickly through asteroid fields and speed over planets.

 

Im not sure if all gauntlets do this but the supernova gauntlets stop you in midair when you punch with it, use it right before you touch the ground. Same with the special move on Nox's sword. Air dash and rocket jump both work too

 

If you want a more flexability you can change the gravity with
/admin
/setgravity {put in any number you want}
/resetgravity
If the gravity is low enough you can use a rocketspear to move around.
Oh and you can change back from admin by repeating
/admin
Another note is that you can change the gravity to minus by putting a - infront of the number.
