Chaos Emerald

The Emerald Blink Gem is a magical teleportation gem that instantly blinks you to the top of any block you are looking at, as long as it is within 10 blocks. Simply right-click while aiming at a surface to teleport there in an instant, accompanied by a burst of green portal particles and an enderman teleport sound at both your departure and arrival points. The gem has a short 1-second cooldown between uses, so time your blinks wisely!
