Grog tries his hand, but feels bad when he rips the magical stone out of the ground, and cat get it back in. Grog smart enough to know he didn’t do it right, only option is to travel the country side and find the real person who will free the sword, bringing it to them rather than the other way around. Grog so smart, this way better idea
When every fight is taking one wild, easily dodgeable swing, then spending a whole turn getting it behind your back to take another swing.
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?”
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.
