It goes like this: As long as within one round where you dissolved 15 or more than 15 light runes, you then able to deal damage to Todd. But if it is CD 1 when you manage to dissolve 15 or more light runes, you too can deal damage to Todd, and then instead of dealing damage to you, he RESET the light runes counting and back to CD 2 again.

If you manage to dissovle 15 or more light runes when he's CD 2, his shield then removed, so you able to deal damage to him, when he's CD 2 to CD 1 from this condition, his shield will not reset, leaving one more round for you to deal damage to him, after that he reset the counting.
