The Rascal's return to the sulfur caves.

Sulfur poisoning (e.g., sulfur dioxide - SO₂) can be accompanied by skin discoloration. This is the perfect moment for the Rascal to return to the game, because his skin is gray.

Since part of the Scoundrel's functionality was transferred to the traveling merchant (e.g., issuing an enchanted pickaxe), it is suggested that the Rascal will not issue items, but rather steal a random item from the player's inventory (hence the name). To get the item back, you need to catch up with the Rascal. Then he will return the stolen item and give you a random precious item that can be obtained in the mines as a reward.

Thus, a parkour segment appears in the sulfur caves, which includes rocks and poisoned water.
