Buy the Numbers
A character-advancement system for fantasy roleplaying games that replaces fixed classes and level thresholds with individual purchases. Players spend experience points as they earn them to acquire skills, abilities, spells, languages, and other improvements one at a time. This allows characters to combine traits from different archetypes and develop continuously between sessions, without waiting for a complete level increase.
替代规则（核心规则变体）基于属性/数值（STR、CON、PER 等）职业制（飞行员、巫师、科学家等）骰子（主要为 d20）
免费，支持网页、Android 和 iOS
