what is not written there is that are not permanent effects.

they expire after 1 round if not renewed.

(while poison expires after 3 rounds if not cleared).

so, if for any reason (a chase dodge, a full dodge or a different random character selection) you are not able to reapply it to the same target during the round, then the following round is no more there.

if was not so this summon would cost 50k ingots easily and not the 4-5k they evalued it here.
