A jutsu with a written effect β blindness, burns, a battle form β spent chakra and left no trace. NPCs carried no conditions at all, so fighting them ran on description alone.
Conditions land β whatever the author wrote into a jutsu is what it now inflicts: stage, penalty, duration
NPCs wound and are wounded β burning, bleeding and genjutsu show up in the scene roster
Fair turn order β someone else always acts between your two posts, and a slain NPC won't rise to finish its line
A stronger arbiter β it brings back an NPC that dropped out, unsticks a frozen one, and revokes a condition nothing in the posts caused
Threefold, not tenfold β investing into a jutsu boosts it Γ3 at most: mastery decides, not volume
Half the jutsu in Chronicles of Konoha carried their effects all along β the scene simply never read them. Now it does.
