I've also had the idea of situational banshee's, but I don't like it. I updated the Item #2's passive, now instead of 10% maximum health, the shield has component of (200 + 10 x level) and also while it's on, it gives you 20 magic resitatance and 20 armor so it'd not be so easily broken. Also when you enter combat, the shield is broken. The combined price got higher, but it's still affordable.

I actually liked your idea of the shield scaling with your level, but your idea was too lategame (30 x level is a little too much) and this item is supposed to be early game.
