Training
/train starts a short combat session built for repeatable progression. You choose an available training zone/opponent, then fight for up to 7 turns using attacks, defense and jutsu. The command has a normal activity cooldown of about 2½ minutes before Premium or regional mastery adjustments.
Training uses your real health, chakra, skills, jutsu loadout and current effects. A generic Ninjutsu action costs 15 chakra and the defensive action costs 8 chakra, so entering with very low reserves can end a run before your damage becomes the problem.
What you earn
Winning training grants XP, ryō, ability points and a chance at training drops. The normal victory pool can include Chakra Residue, Tool Fragments, Chakra Metal, Soldier Pills and the rarer Training Bell. Failed sessions can still return smaller material drops, so a loss is not always a completely empty run.
Successful training also develops systems outside the reward screen. It can advance chapter/quest goals, increase regional Training mastery, contribute to the world cycle and improve jutsu mastery when you use eligible techniques.
Training challenges and disciplines
A session can give you an optional challenge such as keeping enough health, finishing quickly, using Ninjutsu, landing a critical hit or preserving chakra. Completing it can add a challenge reward on top of the normal result.
The current challenge pool includes: finish with at least 50% HP, win by turn 4, use Ninjutsu at least twice, land at least one critical hit, or finish with at least 20 chakra.
As your Training mastery grows, the activity can unlock discipline-focused options for Strength, Resistance, Precision and Chakra. Their thresholds are mastery levels 2, 5 and 10 for the three discipline stages. They change the training focus; they are not permanent character classes.
If /train suddenly feels expensive, check your chakra and equipped jutsus before blaming your level. A balanced loadout usually clears repeated sessions more reliably than four high-cost techniques.
