So since it appears nobody knows any of the vanilla hardness values I thought I’d just put em here for easy reference/linking people. I left out obvious stuff like water source blocks.
Iron strength or stronger includes:
- Block of Iron, Emerald, Coal, Redstone, and Diamond
- Iron doors/Trapdoors
- Iron Bars
- Mob Spawners
- Enchatment tables
- Ender chests
- Structure Blocks
- End Portal Frames
- Command Blocks
Everything listed above can NOT be broken by F/A creatures. Thank you all for being so lazy that I felt I needed to make this rather than just telling you to go to MC’s wiki. I’ll probably update this if MC adds any other blocks stronger than hardness 5.
