Ok, so basically I am a noob at building mob grinders and I need one built on Hellblock for me. That is pretty much it. I will be able to pay you either Hellblock items or net items. And remember, Hellblock doesn't have any water so it may be tricky. Thanks!
i can build one. you have the spawner in the middle and a 1 block wide platform on each side with presure plates or tripwires on it. when the mobs spawn, they get pushed off by pistons.
veggie ask ignsherlock i can show you mine that he build for me when i next see you on, it's prob the best for hellblock
ok, got the parts list over lunch. 6 pistons per floor 8 Redstone Repeaters per floor 1 stack of redstone per floor+extra for lighting if wanted. 6 string or presure plates per floor. I have a multi-floor design, i can add as many spawners as you want. For muti floors, 8 vines(you can place those right?) and 8 buttons Optional redstone lamps for on/off switch. not nessesary but good for mantinence Several stacks of building material(what mobs are you planing on spawning because that varies the amount)
