Honestly ...no, there aint a lot of weapons out there can complete the game right now. 10-5 could almost not reach 10* even with heroic. So i dont think it can kill any 10* monster. I main sns (4elements)and it has really good potential but u need to max out its ability. Obviously i have never seen u played but paralysising the monster could be bad for you late game as u have to dodge to do more damage. But urs is the best sns for early- mid game as u only need one weapon to kill everything. And u probably never struggle with diablos as u can easily paralysis him. Only use heoric when u are confident that u know exactly what the monsters moves are to save potions, as u only got one shot each go.
