Oh no, listen to me! I said Rend when I meant Line, I'm sorry! I can tell you a little bit what Rend feels like, but we can't practice it without your god around, so Line it is.

Anyway, three ways: as a wall, as a long-ranged attack, and as a kind of weapon you keep in your hand to attack with. If that doesn't make sense, I can try to explain more.

[Adrien seems nice and is picking up a lot, but maybe - like her - he's just a normal boy, so saying something like long-ranged attack and weapon may not make sense yet. Okay maybe if he's played a lot of video games in his old life, or watched a lot of TV... never mind, this is why she had to just ask and see.]
