The pearls and eyes should be completely renewable, made of enderpearls and rare mob drops.
Each eye uses another item crafted with it, just one.
Ghast tear = Nether eye
Bubble block = W.D. eye
Pearls use multiple, using a TNT/checker pattern with an enderpearl in the middle.
Each uses two drops(excluding the pearl), alternating.
Blase powder + lava core = Nether
I made a thread about THE CREEP. EVeryone said it was exactly like the end with creepers. i wouldt call it nether eye because people said that was a copy of the end and un original sorry.
