Can be used in the Main Phase of your next turn following the turn in which you took battle damage. Select 1 face-up monster on your field. This turn, the selected monster's ATK increases by half the battle damage received in the turn you last took battle damage. This Skill can only be used once per turn.
The statement "only once per duel" is false.
I just played an opponent who used it in back to back turn after I did 1900/1100 damage in consecutive turns.
Unless this is an older post, in which cade I apologize, but as of Aug. 24th 2017, the skill can be used, so long as you took any battle damage previously.
It might be confused with the fact it doesn't accumulate LP damage taken over time, opposed to the most recent damage taken.
It's awesome with asura priest or Inaba white rabbit
I guess I misunderstood this skill... I took 3000 points in damage (from 3 separate monsters) but when I used this skill it increased my ATK by only one of those monsters that damaged me not by half the sum total of damage.
