Hi, can someone please help me with creating a twin Martial soul? I got an idea to make something like a charge Blade from monster hunter into soul land. One would be a sword and the other a shield. But since deploying both at the same time would be really draining normally, I'm thinking of some mechanic that, instead of burning through spiritual power, the souls would synergize and replenish one another just like in monster hunter phial management

(I apology if there my text is hard to unde. English is not my first language)
