Oddball Sphere

Oddball Sphere is completely immune to fall damage, but makes you ridiculously bouncy (when you hit the ground, you will be launched into the air again). This is similar to Ighant Bulb, but is not limited by time. Unlike the fall damage immunity from Physics Field, the Oddball Sphere doesn't drain energy over time, so you can remain immune for as long as you need.

Be careful when using Oddball Sphere near the core of the planet, because the fall damage is not the only danger there: you can accidentally fall into the core ocean of Lava, and on some Gas Giants even touch the bottom of the world (which results in immediate death).
