Cave trolls are known for their massive bodies and hard skin. They aren't very intelligent creatures, and are often dueling amongst themselves. Although they prefer smashing poor adventurers with their bare fists, it's not uncommon to see a cave troll carrying an oversized club or hurling boulders. If an adventurer happens to meet one, their best bet would be to run away. Otherwise, they might just regret they ever walked into its cave.
