Druid - Circle of Consumption
Circle of Consumption Druid, by Duong Thanh Lam
The Circle of Consumption is for druids who are in the process of forgetting how to be human, and only ever want to be a swarm of ravenous insects. Great at parties!
It fills a similar role as other wildshape-centric combat druids - in combat, it'll mostly want to be in its Swarmshape, which scales up with your druid level so it never becomes obsolete. When you're not Swarmshaped, you've still got access to a druid's normal full-caster kit. Compared to a Moon Druid, the Circle of Consumption doesn’t do quite as much damage in tier 1 and 2 (that’s a good thing), but scales significantly better in tier 3 and 4, where Moon Druids start to fall off.
