A jutsu with a written effect — blindness, burns, a battle form — spent chakra and left no trace. NPCs carried no conditions at all, so fighting them ran on description alone.
Conditions land — whatever the author wrote into a jutsu is what it now inflicts: stage, penalty, duration
NPCs wound and are wounded — burning, bleeding and genjutsu show up in the scene roster
Fair turn order — someone else always acts between your two posts, and a slain NPC won't rise to finish its line
A stronger arbiter — it brings back an NPC that dropped out, unsticks a frozen one, and revokes a condition nothing in the posts caused
Threefold, not tenfold — investing into a jutsu boosts it ×3 at most: mastery decides, not volume
Half the jutsu in Chronicles of Konoha carried their effects all along — the scene simply never read them. Now it does.
