Screenshots, including timer areas (Do not use shaders or a custom resource pack!) :
Any block that you prefer to be no-break or no-drop?: Lapis Block, Iron door as no break. Iron blocks and lapis blocks as no drop
Any extra information about your map?: If Possible I would not like emeralds to be used because emeralds will somewhat ruin some things in the map. I would like the command blocks to be set to Nausea I for 10 seconds and Weakness I for 10 seconds. There's a dungeon in the map and at the end there's two chests, with what is perhaps OP stuff, Only one can be opened due to how the redstone is set up. There's spawners in the caves, dungeon and buildings. If needed I can explain further. There's likely a couple flaws I was unable to notice due to the vastness of the map.
