86. I meant to ask about that: obviously on a skyblock, simple mob spawning towers are easy; is there a way to guarantee their effectiveness in a normal world? Would you need to dig around them to make sure there are no other valid spawning locations?85. For gunpowder make one of the giant vanilla mob spawners, use conveyer belts to sent them so far to the ground they die.
Optional: put creeper spawners inside the tower
In 1.7.10 I really liked alumite an electrum, but you'll have to go with knightslime. I BELIEVE I did knightslime on top, electrum on bottom, but i may be wrong. (and yes, it does make a difference) Firestring too. for arrows, I think it was slime arrowhead (maybe manyullyn????) blaze shaft, and paper fletching. add quartz to the arrows, and redstone to the bow. Pretty nice I say.86. Even in TiCon2? I haven't dabbled with those yet. Any recommendations?
I've decided though, that I just enjoy IE so much at the moment, that I really want to give its tools a proper go though I think I'll still go AA drill, because that's just SO nice.
