[He's vaguely familiar with the Force, but only Rey seems to know much about it and it isn't a topic that comes up often. He doesn't know enough to argue whether or not it's similar to magic, so he'll let Luke draw the comparison.]

Different spells take different things, sometimes it's a gesture or a word, sometimes it's a handful of diamonds, depends what you wanna do. [If he were a normal D&D wizard, almost all his spells would need all those components, but he isn't and they don't.] As for focus, I mean - if you stabbed me I wouldn't be able to keep it up but this is background noise for me right now. Can't really do two spells at once and I got a limit of how many I can cast without resting, cause they eat up my energy same as any sorta exercise. But something like this doesn't need to be channeled continuously.

[Please don't stab him to test this.]
