Ah, so it wasn't a helpful dive, but slow sinking. Hmn.

Yeah, he doesn't particularly like barrier blastia. And even then, Duke is aware that it would have to be built for something like keeping out salt water, rather than monsters.

Duke pauses in mid sorting, eyes focusing on something else. Wait, they had already combined foreigner magics into a spell. If another of the mages here had a way to make a stable power source, or perhaps just a container that others could charge - like Duke and Yuri with their Dein Nomoses (... is it supposed to be Dein Nomi? Duke shoves that thought away, it wouldn't matter on Terca Lumireis, and honestly wasn't what he was focusing on-) Part of the problem with salt water - or perhaps ocean water - was that it wasn't just water and salt mixed to the right levels, but there was other things in it... If he could allow for the change in water...

Sorry Yuri, Duke is lost in thought now.
