While I have no stories myself my niece had a hilarious death she told me about.
While out exploring she happened upon a cave filled with trolls. She was doing well, dispatching trolls with relative ease with her massive war-hammer however she eventually ran out of health potions but thankfully only had one troll left.
She quickly slaughtered the beast however her health was dangerously low. Just as she was putting away her weapon a mudcrab popped out of nowhere and attacked! She was so startled she stumbled backwards, pulling out her weapon BUT falling into a pool of water sheathing her weapon!! Before she could react and get out of the water, plus pull out her weapon, the Mudcrab was already making a lunch of her

My niece, the killer of trolls who dies to mudcrabs!
