It's really good for mob farms, love it. However it seems that player armor isn't taken into consideration, we set it up to do 3.5 damage so it's between lava and a soul campfire. But a player will full netherite dies in the same amount of time as a player with no armor.
The idea was cool but it's implemented on purpur server you can add more functionnality like drop a log bloc to have planks yes it's cool plugin if you add that ^^
