--_ Magiglass Tower Shield _--
A transparent shield made of special glass, that has all the properties of a bulletproof riot shield.
Though not immune to magic, these special shields block line of effect and sight for the purposes of magic. For example, the heat of a fireball could potentially go around the shield if it were big enough, but it would protect against a cockatoo's gaze attack, and something held in telekinesis would be released if the shield intersected between the item and the unicorn.
 
--_ Powder _--
Doesn't taste like powder, but when eaten, it makes the user say "Hmm, tastes like powder."
