Strange that i just level'ed Crusader through Shield boomerage. Will upload video later as one data is corrupted lol
What affects SB damage
1. Shield weight
2. Weapon ATK and refinement
3. Cards (Race, Element, Size) However, Archer skeleton works best but it's kindly to be the most expensive card, yet, most versatile one.
4. Ranged mods work (best actually)
5. Converter works.
Good luck. For me, I would just use +9 Pike with cards and Stone shield lol
Note, my hunch tells me that Shield refinement doesnt work. I will have to quickly test it later.
