I failed miserably on my creeper spawner rooms. Im redoing every room and I need suggestions. My grinder will have 4 separate rooms with 6 spawners in each of them. Im asking for what dimensions each spawner room should be and how far apart each spawners should be from each other. Also give me a suggestion on what blocks I should use for the rooms and maybe patterns on it. Maybe even pixel art on the rooms while im at it. I want the rooms to be not dull so give me blocks that would make it unique. Remember, Im in .org so give me suggestions that wouldnt cost me over 100k.
