Blackmoor D&D 4th Edition: The Inventor Class
This roleplaying supplement introduces an inventor class for a fantasy setting. Characters rely on clockwork, steam, gears, springs, alchemical reagents, and conductive coils rather than arcane magic or divine power. Players create engineers and scientists whose devices provide abilities and combat options comparable to weapons and spells.
骰子（主要为 d20）等级制（获得经验值并升级）基于属性/数值（STR、CON、PER 等）
免费，支持网页、Android 和 iOS
