(OP!) That sounds like a fine combination. I don't really have a preference so have at it A!A :D

(especially because I can sort of see Marcurio having a vague idea of what word walls might be about from legend. So when the DB asks if he can hear anything he makes up some grandiose explanation that "of course he can because he's a master wizard" and then the DB calls him out on it.)

But, i'm sure you have your own ideas so i'll just stop now. XD
