I dunno, five minutes? Is this from world start? If you need a nether star, this is typically an hour's work to find a wither skeleton source, and a couple hours to get 3 skulls, but ~1 minute to summon and kill the wither.Nether star for moving the spawner to my base. Yes, you can turn off the spawner with torches, but this is feed the beast ffs... The thing about ftb is making things a little more complicated.. I make spawner that do not need my attention, not swords, no torches, no nothing. But i make them with vanilla spawners because using mrf or soul cages seems too op for me, is that hard to understand? And where is an exaggeration to say that you cna make an autospawner in 5 minutes? do you play with a broken mouse or what? If i had what it needs i would make a video of it just to show you how easy it is xD
Mind you, the Portaspawner is insanely overpriced for what it does. And you seem to be an Eagle. Well, almost one, you seem to be cunning enough to use the ctrl key, but stil..
