Hard Glass

Hard Glass is a craftable block that has very high Blast Resistance, similar to the Blast-proof Glass block in another Hypixel Minigame named Bed Wars. Unlike regular glass, it drops itself when broken without Silk Touch.

This is incredibly useful for Ghast and Creeper Farms/Minions.

Bugs
Hard Glass was used for a bug where you could place Minion Heads on the block. This has been patched.
