Low Magic Age

The d20 SRD, two ways

Low Magic Age is a long-running indie RPG from the small studio Hangousoft, built on the d20 / OGL System Reference Document — the same 3.5-derived open ruleset behind Knights of the Chalice and Pathfinder. It splits itself into two complementary modes: a tactical Battle Arena of self-contained turn-based encounters, and an open-ended Adventures mode in which a party explores a procedurally generated low-fantasy world, takes on quests, and grows over a full campaign.

Its rules come from the published d20 OGL lineage rather than a WotC license, so it sits among the catalog’s unofficial entries alongside the other OGL CRPGs.

Gameplay

Combat is faithful turn-based d20: classes, feats, and spells map closely to the SRD, and tactical positioning, action economy, and item management decide fights. The Adventures mode layers a roguelike-flavored sandbox on top — randomized maps, item economies, and an open world to roam — giving the same ruleset a far longer, less scripted shape than most CRPGs. The game spent years in active Early Access development, steadily widening its class list, spells, and world systems.
