By default, there are no limits on how experience rewards may be spent to improve a character. The Improvement Limits Feature deepen a character’s connection to The Pattern but limits character development/Feature acquisition and uptake in multiple ways. They must spend time progressing theories, knowledge and understanding. IF not direct experience, this usually is represented as quiet and uninterrupted time, in a place where they can contemplate and test themselves. This reflects the “Gritty Realism” of the Incarna Approach to Character and Story.
i20 [specific] Requirements:
An increase in level matures the outlook and knowledge through practice and experience. It allows new insights and deeper focus into related materials that unlock new capabilities.
LEVEL-UP: The GM rewards a character a level based on Merit. By default, i20™ assumes by campaign milestone and limited by Experiences using Improvement Limits. Multiclassing follows i20 multi-class parameters in addition to the base requirements. Sanity increases by 1 every 4 character levels.
