From the publisher:
In the dark, wild places far below the wave-flecked flanks of a forlorn, wave-lashed island lurk the degenerate troglodytes of the Tentacled One. Dwelling amid the tumbled cyclopean ruins of a forgotten epoch, the troglodytes toil in their labyrinthine, stench-filled caverns at the behest of their bloated, tentacled master. Emerging on fog-shrouded nights when a sullen, gibbous moon hangs low in the sky the troglodytes raise their croaking voices to the ebon heavens in terrible, half-forgotten rites of veneration to unknown, elder beings.
Troglodytes of the Tentacled One includes:
Six feats
Two new class features
Four spells
Two magic items
Twelve stat blocks (ranging in CR from 1 - 9)
A new template: the degenerate creature
Troglodytes of the Tentacled One is written in the Lovecraftian style of elder horrors lurking beyond the light of civilisation in the dark, wild places of the world.
