lmao haha, i mean that makes sense but giving to the fact that merchant doesnt know how to fight and get a combo he cant use it
i also would describe merchant as a scrambler/archelologist who just discovered ancient gaulish artefacts and now just sells them, because profit

but since asterix is a gaulish individual tied to a specific culture and gods, only they know how to use the artifacts of ancients at his own advantage
its sort of like gaulish gods give him semi god powers in the right moments
