On a scale from having the whole team choosing red as their null suit colour when their old uniform before their mindwipe was also red to having a magical umbrella that absorbs the power of defeated magical energy when you yourself are a lich, that’s about as ironic as dying by the hands of your own meat monster as the wizard who’s been calling you a shitty wizard is proven right.
What I think I’m saying is that The Adventure Zone is quite a big fan of dramatic irony for a mostly-unscripted D&D podcast.
