Swarmkeeper Ranger Guide for Beginners: Mastering the Swarm in D&D 5e

The Swarmkeeper Ranger is a master of nature’s tiny creatures, commanding a mystical swarm of insects, birds, spirits, or even spores to fight alongside them. Introduced in Tasha’s Cauldron of Everything, this subclass is perfect for players who want to play a ranger with supernatural battlefield control, mobility, and sustained damage through a living swarm.

Unlike other Rangers who focus on direct damage, Swarmkeepers excel at pushing and pulling enemies, repositioning themselves with magical swarms, and dealing extra damage with their living allies, making them one of the most unique and tactical Ranger subclasses in D&D 5e. If you love the idea of harnessing a swarm of creatures—whether bees, ravens, spectral spirits, or faerie lights—to overwhelm your foes, this subclass is for you!

Why Play a Swarmkeeper Ranger?

Key Benefits

• Best Ranger for Battlefield Control – Push, pull, or reposition yourself and enemies with your swarm.

  3. Move yourself 5 feet in any direction (no opportunity attack).
