I also have a Lightning Master swordsman dual kat but I dont yet have the same amount of Lightning damage to stack for it and it only has A skill scaling so its damage is substantially less but it does have a roll for additional damage from Sign of the cross so that particular skill hits really hard. Tengen Kujaku 1st / Kara Jishi 2nd (You can Swap Tengen for Suzaku for even more fire dot damage but I prefer the bigger on hit damage boost from tengen)
