Fantasy Grounds - The Hole in the Oak is an old-school fantasy RPG adventure module designed for virtual tabletops on PC. It delivers a classic dungeon crawl experience set in a root-riddled complex beneath an ancient oak tree, where players explore twisting passages, wizard chambers, and an underground river tied to a former reptile cult. The module supports characters of 1st to 2nd level and emphasizes exploration, resource management, and interaction with the environment in the style of vintage adventure games.
Gameplay
The core loop revolves around navigating a 60-area dungeon presented in quick-reference bullet point format. Groups descend through the entrance shaft into sandy-floored chambers and winding tunnels, where descriptions highlight sensory details like hoof prints, swaying roots, or distant chuckling to aid natural narration. Random happenings occur on a 1-in-6 chance per turn, introducing events such as burrowing roots or ghostly wizard projections that enforce boundaries or deliver rumors.
Factions and inhabitants create dynamic situations without scripted plots. Troglodytes, ghouls, sheep fauns, gnomes, fishing lizards, and root faces occupy distinct zones, allowing for alliances, conflicts, or avoidance based on player choices. The map features multiple loops and interconnections that reward careful mapping and provide escape routes or flanking opportunities. An unlabelled version supports VTT use, while rumors and a loot summary help prepare sessions or expand play.
Mechanics align with Old-School Essentials rules, focusing on procedural dungeon crawling including torch management, reaction rolls, and morale checks. The design encourages ingenuity over direct confrontation, with deadly traps and encounters that punish rash actions.
Game Modes
Play centers on expedition-style sessions for small parties of low-level characters. Groups can tackle the location as a standalone adventure or link it upstream to another module for a larger three-level complex exceeding 115 keyed areas. Sessions typically involve mapping, faction negotiations, and resource tracking in a single connected environment rather than separate competitive or story-driven modes.
The structure supports repeated visits with changing outcomes due to the non-linear layout and random elements. Referees run the content in Fantasy Grounds using the free Old-School Essentials ruleset, with options for solo preparation or group play through the virtual tabletop interface.
Key Features and Design
The adventure includes a rumor table for initial hooks, background details on the wizard complex and cult ruins, and suggestions for expanding downward with additional levels. Bullet-point keying keeps information accessible during play, while the included map aids visualization of loops and vertical connections like the underground river.
Monsters and hazards draw from classic B/X sources, including variants like tree babies and evil stumps that react to player presence. Loot distribution supports progression from 1st to roughly 2nd level for a standard party, with treasures hidden or guarded to reward thorough exploration.
Is It Worth Playing?
Reception highlights the module's strong layout and replay value for old-school enthusiasts. Reviewers note its effectiveness as an introduction to procedural dungeon crawling, with factions and interconnected areas that foster player agency and varied outcomes across sessions. The quick-reference format reduces preparation time and supports improvisation at the table.
It suits groups interested in low-level fantasy exploration with deadly consequences and opportunities for clever problem-solving. Availability on Fantasy Grounds makes it accessible for virtual play, and the design holds up for both one-shots and short campaigns. Players seeking linear stories or high-powered mechanics may find the focus on classic procedures less appealing, while those who enjoy mapping and faction dynamics often return for its depth and expandability.
