Later in the game, Xander is going to function as an off-tank. However, he will focus mainly on dps, via his blade(s?) and buffing the party with his tech and debuffing enemies with his gun(mainly). So yeah. General idea for him is...

Novice > Gadgeteer > Technoblade > Machiknight

So yeah, he isn't a dps caster. Sorry xD
