Just have them all up all the time and don't worry about it *grin*

I don't know if it's missile shield or magic screen that make you resist the effects like webbing and sprays and squirts, but if you have both up at all times, then you don't have to worry about which is which. I just kept armorplate, enchanted blade, missile shield (which is a must against the plants anyway), and magic screen going at all times. It was a little trying on the mana for my bishop, but not as bad as all of the damage that you'd have to heal without them up. With all of those up, I very rarely had to worry about my party from arnika on to the end of the game. And hey, if you have a gadgeteer, you get x-ray, armorplate, and detect secrets (if you want it) for free.
