How to Build Nether Portal for Minecraft PE

You need
1x nether core reactor
4x gold block
12x cobble stone

Make a plus sign with 5 cobblestone and put 4 gold on the edges

Place nether core reactor on middle cobble stone block

Make another 5 cross ontop of the portal same as the bottom

Put cobbles stone ontop of the gold on all 4 like so

I would have atleast iron armor and gold sword if you want to kill the zombie pig men Or just cut your difficulty down good way to get semi- rare stuff especially gold dust
