User blog comment:XCaidx/Gumi's advisory about Rugal's type/@comment-27362456-20160730143103/@comment-27180297-20160731011046

씨발 is right. However 11-15% is good enough to get ready for your nuke or at least I find some. I refer to this area has the optimal. If you have a good Light Type Nuker UBB with it and when you kill Rugal and he ressurects just use a Hero Crystal followed up with a fujin to use the UBB once more to finish off his ressurected 11%. If you are unsure that you can finish off the last of his 11% use an angel idol/idol effect. Mitigation will not cut it when he slams you with the 999999 dmg atk over and over again.
