An Ender Pearl is obtained by killing Endermen. But it can also be crafted using 4 Iron and a Minium Stone, or in a Carpenter with 5 Pulsating Meshes. It also has the unique ability of teleporting players to whereever it is thrown to, at the expense of taking a small bit of damage upon arrival. It is also one of the ingredients in an Eye of Ender.
Please note that this receipe only works with Ender Pearl Dust (Portal Gun Mod), not the Dust from GregTech.
If you place 5 Pulsating Mesh in a carpenter in a plus shape, you will get an ender pearl. An Ender Pearl requires 25 Mysterious Comb in order to craft using this method. Please note that this recipe does not require any water.
This receipe creates the Ender Chest from the Ender Storage mod. Not to be confused with the Ender Chest from Vanilla Minecraft.
