Sustained Combat Governance
This page governs:
How injuries persist
How chakra exhaustion affects performance
How extended missions degrade effectiveness
How recovery works
Shinobi are elite.
They are not immortal.
Spell slots represent chakra.
However:
Running out of spell slots is not the only exhaustion state.
Introduce Chakra Strain Levels:
Level 0 — Stable
Level 1 — Minor strain (disadvantage on concentration checks)
Level 2 — Moderate strain (reduced movement or minor attack penalty)
Level 3 — Severe strain (disadvantage on physical checks)
Level 4 — Collapse risk (Con save or fall unconscious after exertion)
Strain accumulates through:
Overcasting
Bijū use
Forced high-rank techniques
Multiple encounters without rest
If a squad operates without proper rest:
Apply progressive fatigue:
After 1 extended mission:
Minor strain increase.
After 2 consecutive high-rank missions:
Reduced max chakra recovery.
After 3:
Forced rest required or risk injury.
War accelerates fatigue frequency.
When reduced to 0 HP:
Roll for Injury Outcome:
Minor wound (scar, temporary penalty)
Structural damage (reduced stat until healed)
Chakra network disruption
Lingering nerve damage
Temporary technique restriction
Not every downing causes injury.
But high-damage hits increase probability.
This prevents reckless play.
Healing must:
Consume chakra
Require time
Be limited by skill
No infinite battlefield healing loops.
Severe injuries require:
Downtime
Hospitalization
Specialized treatment
Jinchūriki using cloak states must:
Immediately gain chakra strain levels.
Partial manifestation risks:
Internal injury.
Full manifestation:
Guaranteed severe strain after reversion.
Using S-rank techniques:
Forces exhaustion check
May impose temporary debuff
Cannot be spammed
High-tier techniques must feel costly.
Genjutsu battles and mental strain may cause:
Concentration vulnerability
Delayed reaction penalty
Emotional instability
Mental exhaustion matters.
After:
Major battle
Bijū exposure
Severe injury
High-strain missions
Downtime must occur.
No immediate mission stacking.
During high global tension:
Rest periods shorten.
Risk increases.
Injury frequency increases.
Medical capacity may be strained.
War reduces safety margins.
Before applying no-consequence recovery:
✔ Was chakra drained?
✔ Were high-rank techniques used?
✔ Was there significant injury?
✔ Has sufficient rest occurred?
✔ Is this war-time?
If not justified:
Do not fully restore.
