Iron Heroes

Iron Heroes is a variant Player's Handbook for the d20 System of role-playing games, in the tradition of Arcana Unearthed. It incorporates the core d20 mechanic, while introducing new rules options, differently-balanced classes, an entirely new feat system, and changes to the way skills and feats operate. It is intended to allow players to take on traditional challenges at the same levels that their D&D counterparts would be able to, without recourse to magic items or high spellcasting. It was written by Mike Mearls, is currently owned and updated by Adam Windsor, and published by Fiery Dragon Productions.
