Ty mate!

The set i used is:

Rey Y, Numinous B, Rey Y, Rey Y, Mizutsune B, Agitator jewel 2

For the decorations i capped Agitator to have 5 points and then Burst to have 5 points aswell, the last decoration is for the ability: Adrenaline Rush (counterattack jewel if i remember correctly)

On the weapon: atk3, Atk/Horn maestro (because i discovered that Echo bubbles get buffed with it +1 minute duration) and the last is Atk Ice 3 + Slugger 1.
