Unlike the Beast Master archetype, the swarm provided as a Swarmkeeper grants you additional abilities in combat that you would otherwise not have access to. This can mean doing additional damage, sliding in and out of attack range, and even gaining additional spells.
As a Ranger, your role is to support your party by filling various gaps. Whether it’s the need for extra damage, another front-line warrior, or nature expertise, the Ranger, especially a Swarmkeeper, offers unique utility and long-range damage abilities.
