Oakling
This roleplaying supplement introduces oaklings, a playable species of medium-sized living trees with leafy faces. Industrious, logical, and unconcerned with sentiment, oaklings pursue their own advancement rather than protecting nature. They may serve benevolent rulers, ruthless tyrants, or follow their own causes, reflecting nature’s unpredictable character.
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）
