Our best battle had no actual fighting
in our first campaign we had to scare a dragon out of a town, we didn’t need to kill it, just scare it off, lacking a tank we were reluctant, but went anyway, what followed was glorious.
Bard (me): What do I roll to scare it away with my bagpipes?
Necromancer: wait hold on I need to do something
Bard: please just let me try this I-
Necromancer: No just wait *casts mage armour on me, subsequently making me glow* there,
Bard: Oh, thanks, ok now what do I roll to scare the dragon? performance or intimidation?
DM: *with a deep sigh* I guess intimidation
Bard: *rolls a 23, not a nat but still good enough, everyone is screaming* I SCARE THE DRAGON OFF BY PLAYING ‘YE OLD SANDSTORM'
DM: *Even more sighing as everyone else, including me, is still screaming*
We all leveled up after that too, it was a beautiful session
