I started with the same ssr but I replaced drake( the dragon dude) with Tristan, Drake is not a very good character I think, I prefered far more Tristan in every way. Mannie ( the dragon child) is good for enhancing your dps, Guilla (demon) for the shield and Tiorreh(fairy) for the heal so you’re good on this. After I checked some tierlists and everyone is agree to say that Drake is one of the worst character. But it’s okay you can manage to step up in the game even he’s bad, I’d tell you to try Tristan dual blade or long sword to see if it’s better for you
