I was just reminded of the time my party was fighting an Invisible enemy, and none of us had any way to reveal the invisible person. Except for me, now the issue was, I was a Druid/Rogue. Which meant my spell save dc was garbo, so casting Faerie Fire wasn't going to work. So instead I Wild Shaped into a Giant Spider to point to where the invisible person was. I am curious to know if other people have similar 'well this was happening and this worked' scenarios.
