Regenerating Blocks are an extremely dangerous tile found in the Sunken City.
Regenerating Blocks appear much weaker than most tiles, as they break in a single hit of a whip or any other weapon. However, they reappear after 5 seconds of being destroyed, crushing anything occupying the same tile space instantly. This means that items will be instantly destroyed and irretrievable and entities will be instantly killed.Players will have to move through Regen Blocks as part of the main path in the Sunken City, making carrying items like Hou Yi's Bow or escorting others like Hired Hands or the Eggplant Child a stressful task.
The Regenerating Block is a rather annoying block found inside The Worm. They can be destroyed with most attacks, but after a few seconds will reappear at the same spot, killing everything inside it, similar to the teleporter. Broken regenerating blocks will be distinguished by a backdrop version in it's place. They can be one of the most frustrating and annoying block inside The Worm in dire situations, as you will get trapped by them and will most probably die.
Tips for getting past them.
To get past them, try placing bombs down, getting out the blast radius and running through as quickly as possible. (A Mattock is also very useful.)You can also use your whip to break them. Sometimes they will also spawn in big chunks with some gaps in between, and you need to be careful with these structures.
