5e x 5 OGL SRD
A text-only set of PDF rulebooks converts 5e into a d100-based roleplaying system by multiplying attributes, skills, and saves by five. It retains the original combat damage and hit point system for compatibility with other d100 games, while incorporating material from the 5e, 3.5e, and other OGL sources. The collection includes rules for characters, spells, equipment and treasures, combat and conditions, and monsters. The files are minimally formatted, single-column PDFs, accompanied by additional PDFs and an Excel spreadsheet.
基于属性/数值（STR、CON、PER 等）等级制（获得经验值并升级）骰子（主要为 d20）
