"Improvement: At Rank 5 the Renewed Vigor also restore a number of wounds to the Battle-Brother Equal to his rank." Lasting for a Number of rounds Equal to his Rank.

My question Is which statement is Correct of the Following?

A. 5 wounds and have the other effects of Renewed Vigor for the rest of its duration

B. 1 Wound per-round along the with the other effects of Renewed Vigor.

C. 25 Wounds (5 Per-Round) along with the other effects of Renewed Vigor.

A. The base effect lasts for however many rounds. Upon improvement, the user gets a one-shot infusion of Wounds, and the other effects continue for however long.

Agreed with Kshatriya.
