I don't think they get anything vs constructs. I mean, if I make my water dragon and have it charge Kotori (sparring, of course), it's the same as if I grabbed a torrent of water and hit her with it. They're immune to magic, but physical objects being controlled by magic are still a problem. You're immune to magic, but Sir Isaac Newton will still kick your teeth in.

You named your Water Serpent Construct Sir Isaac Newton? Fine. I will name my sword "Apple".

And that is a question I've been mulling over. If a mage summons a wall of stone, cam I just phase through it because it's magic? It's all very peculiar.

I think you're right there, it makes sense at least.
