Jack Horner did that in Puss in Boots 2: “Excalibur! I couldn’t get this rock off of it, but it’s still pretty cool, right?”
(from Tom Fischbach, creator of Twokinds)
This reminds me of a comic I saw a while ago where the BBEG was gloating that he could only be killed by the sword next to him that couldn’t be pulled from the stone. The barbarian picks up the BBEG and swings him at the sword.
For the entire campaign Grog should be followed by some snot nose kid and a wizard who keep trying to steal the stone.
Grog wakes up one night to find them trying to steal his weapon, and the twerp can’t even lift the handle off the ground. He picks up the hammer by the head and spins around to dislodge the kid - which works, insofar as the child flies off toward the mountains, holding some kind of sword. Grog wonders where he got that, and goes back to bed.
at the end of the game, the wizard or the mucus child should be able to take the sword out of the stone
Then the sword is the chosen one… :)
it would be even funnier if it’s a fighter with the barbarian archetype (pf2e) or 1 level of fighter and the rest of barbarian (dnd) so that their lore is someone who was trained to use a sword but couldnt, so started raging and getting stronger to use that hammer
