+Invisibility Potion by TenPlus1
+
+This mod lets you craft an invisibility potion using 1x Nyan Cat and 1x Glass Bottle.
+
+Use potion to hide yourself AND nametag (0.4.14 dev only) for 5 minutes.
+
+Server admin can use the '/vanish <name>' command to hide/unhide players or themselves by leaving it blank.
