Enderminy's are very cool indeed. In Direwolf modpack, I have a small island near my base that is Ominous Woods biome. At night, I can fly there as a bat and change back into myself, then I can stand on the beach and hit one Enderminy and immediately retreat into the water. Standing in the water, I can hit the Enderminy's as they all come at me, however they cannot hit me because as soon as they run into the water, they teleport back onto land!!! I'm collecting my ender pearls this way without having to get to The End and deal with the dragon (haven't even found a Stronghold yet).
Oh, a question - has anyone experimented between a Tinker's Construct sword with Looting III on it, and one of those Ender IO swords that the description says "increased ender pearl drops". Which of these swords will provide more Ender Pearls? I haven't tried comparing them yet.
don't the enderminy's attack creepers aswell? I had quite a few holes around my world as I'm guessing the enderminy's attacked the creepers who then exploded
