The Bug
When a pointed dripstone falls on a player with a helmet, the helmet loses a lot of its durability.
How to reproduce
Put on a new netherite helmet
Go into survival mode
Stand centered on a block and run these commands in order:
/setblock ~ ~30 ~ minecraft:dripstone_block /setblock ~ ~29 ~ minecraft:pointed_dripstone[vertical_direction=down] /setblock ~ ~30 ~ air
If you don't die, take a look at your helmet
❌ notice it took a great deal of damage
❌ if you tried a new leather helmet, it would break on first try
Do you mean in terms of durability, or hp dmg?
