So it is intended that sculk blocks are only useful when a player is advanced enough to use the unintended feature of trapping a wither in bedrock?
This makes sculk XP farms completely inaccessible to the average player. Even if this prevents tnt duplication abuse it just makes the entire sculk XP mechanic absolutely useless...
Please think about this.
@aceplante The problem is that you don't get enough xp. Most technical players thought this mechanic would be the intended replacement for AFK Zombie Piglin farms because Mojang said they wanted to remove them in the future. But because of this "intended feature" AFK sculk xp farms become very inaccessable because you have to trap a wither in bedrock to do it. If you have to manually blow up a bunch of sculk blocks to get (very little) xp you might as well just fly to your endermen xp farm which is much much faster.
As they are right now, sculk block XP farms are not a viable replacement for AFK Zombie Piglin farms.
