Endium Tools have about the same durability as stone, and mine faster than stone. However, they have the ability to bind them to an inventory, and everything mined is sent to that inventory. Does not work cross-dimension (yet). Endium tools currently cannot be repaired. The reinforced versions of these tools work the same way, but have more durability. All tools are crafted using Endium Ingots and End Stone Rods, which are crafted the same way as sticks are, except with endstone.
The scythe gives a 100% chance for a mob to drop a head. This mod adds the heads of other vanilla creatures; Blaze, Enderman, Zombie Pigman, Spider, Cave Spider, Pig, Cow, Mooshroom, Sheep, Wolf, Villager, Chicken, Chicken, Witch, Zombie Villager, Iron Golem, and Squid. Unlike the Endium Tools, the scythe can be repaired in an anvil.
