Mending will always remind me of the one 3.5 game where we were all pinned down behind an overturned cart by goblin archers. When things got too quiet, we wondered whether the coast was clear, so the rogue grabbed the bard’s lute and (like a classic cartoon moment) stuck the head of the instrument over the top of the cart like it were a person peering over. When an arrow slammed into it with a discordant thud, we knew that we had to escape by an alternate route. However, as we got ready to sneak away, we saw the bard beginning somatic spell gestures (the player miming the same). As we all turned to him incredulously, the sound of approaching goblins getting closer, he said a line that has become legendary to our group...
“Wait, I’m mending my lute!”
(The same player is also known for shouting, in character, “I’m using diplomacy!” as his paladin tried to make himself heard over the din of battle in another game, as if that would convince the enemies to stop fighting and listening)
