I wouldn't say common, but it was also... not uncommon? At least where I come from, I mean. It took a special kind of blacksmith and the right materials, but you could imbue any kind of weapon with magic, from swords to lances and even bows.

Aside from that, you have stuff like the Heroes Relics-- they're not exactly magic, and only people with Crests can wield them to their full potential, but they have all kinds of special abilities in combat. And then you have stuff like my sword, which not even the more scholarly people in Fodlan could explain beyond telling me it's definitely not like those Relics...

[ There's a bit of frustration at that last part, but he's quick to shake it off. No use dwelling on his personal mysteries now. ]

Honestly, just saying that all out loud just makes me realize Fodlan must sound real weird to any outsiders, huh?
