From publisher blurb:
The Stalker is an undead ranger who has achieved immortality through their mastery of the hunt and their devotion to the wilds. Their skeletal body is draped in decaying leathers, and their eyes burn with an eerie green light. Once mortal protectors of the wilderness, they now roam their territory as relentless guardians, hunting and eliminating any intruders. Their connection to nature is deep, allowing them to command the wilds to their aid while moving with the silent precision of a master hunter. The Stalker is a fearsome presence in the forest, an embodiment of nature’s wrath against those who dare to trespass on its sacred ground.
Like the Lich is an Undead Wizard, this is an exploration of other 5e Classes into undeath and eternal life, including background and stats.
