Once per Long Rest, a player can go beyond their body’s limits and perform a tremendous feat. Beware however, as going beyond the body’s limit comes at a price.
A player can use this mechanic to replenish a used class or subclass feature, (e.g. Action surge, Rage, Divine Sense, etc.) cast magic even without spell slots, or perform an act that is not normally within the bounds of the rules(Within the DM’s prerogatives if they allow certain actions or not.) ****Your body however pays the price for this feat, and takes damage for it.
Your body cannot resist this damage, nor can they ever get used to it as they grow stronger, as the feats you perform only increase in both power and risk as you grow.
See below chart on how much damage the player will take upon Going Beyond.
