The 黄马掌气球 is an 配饰 that allows the user to jump higher and double jump when worn. It also grants full immunity to fall damage. The double jump is more akin to 火箭靴 than it is to a 云朵瓶, as the jump button must be held down for maximum effect. The double-jump goes higher than both the 白马掌气球 and the 蓝马掌气球, and wearing it with other double-jump accessories will allow multiple double jumps.
- The double jump can be stopped midway by letting go of the jump button, or by hitting a ceiling.
- None of the Horseshoe Balloons can be crafted with an 黑曜石马掌. The original 幸运马掌 must be used.
- Although it can be worn with the other horseshoe balloons, doing so is pointless, as the extra jump height and fall reduction will only be applied once.
