From publisher blurb:
Discover new druid and ranger archetypes!
Like prior entries Tome of the Pact and Book of the Path provided new options for 5th Edition warlocks and barbarians, Leaves from the Circle brings exciting new subclass options for the druid and ranger classes. Inside these pages, you'll find:
Circle of the Augur: Read the omens across many oracular disciplines, from tea leaves to organs.
Circle of Rot: Cover yourself with the stripped flesh of fallen foes, gaining monstrous protection and unsettling powers
Circle of the Starless Void: Choose an eldritch transformation and whisper madness as you emulate alien life from beyond the stars.
Circle of the Yoke: Aid your community with this agrarian Circle focused on help and home.
Light Cavalry: Your ranger darts between foes, leaving them hobbled and exposed to your allies' strikes.
Thunderstone: Unleash the power of the storm as your ranger electrifies opponents.
Trail Keeper: Bring aid and comfort to your companions in the midst of battle and hard days in the wild.
Vermin Dancer: Even death won't free you from the bond you share with the rats and flies.
Weapon Weaver: Become a relentless barrage of deadly strikes when you become this master of two-weapon fighting.
In addition, explore a selection of new magic items and two d20 trinket tables for your druid and ranger characters!
