On August 15, 2019, Wizards of the Coast released an Unearthed Arcana featuring two new subclasses: the Path of the Wild Soul Barbarian and the Way of the Astral Self Monk. One of the Wild Soul’s Barbarian class features is really…wild. It’s called Magic Reserves and it works like this:

Massive credit to Ben Petrisor and Dan Dillon on the concept. The flavor just comes bursting out of this mechanic. In fact, it’s so flavorful I think it can occupy a greater design space. If you flesh out this concept, you can build an entire subclass around it.

With Unearthed Arcana (or any playtest material), the designers tend to overbuild. Then, when you receive the feedback, they can trim the fat and you wind up with a really nice final product with features that everyone playtested. This runs a little risk of disappointing some folks who liked features…
