MOB TOWER IS IN ITS FINAL STAGES!!!
This is a group effort!! massive project!!
all we are doing now is building a series of identical floors going up to the sky using cobble stone
If you need to mine more stone do so AROUND a spherical 128 block radius from the mob spawner and eradicate all monster spawning capability!, flood with lava/throw torches/ use 1/2 steps etc!
We also need a CONSTANT stream of wood supply and people to place signs, personally I have placed about 7-8 floors worth of signs this is the slowest part!
The spawner will work!, i dropped about 3 skele worth of bones a zombie and i saw 3 creepers get killed and that was at a reduced capacity with sunlight shining through half of it!!! This is a good sign! and that was BEFORE we add about 8 more floors and still going!, the floors are not effective without the signs though!
That is the biggest thing cause it will take the longest SIGNS SIGNS SIGNS!! It goes by FAST when everyone pitches in!
I remember when the mob spawner was just an ocean... we filled a 30x30 pit and dug it to bedrock and are now shooting towards the sky! Everyone has been doing alot to pitch in!
