So I was reading through the book while thinking about rote spells for a character and the part about offensive blocks caught my eye. I decided to make a spell that would hold somebody (I.E. a block that prevented someone from moving). Days later I used it and it was less than effective, I couldn't draw enough shifts of power to make greater than a 5-shift effect at the time and 5-shifts really isn't that hard to meet or beat for someone remotely skilled and then the block is gone. A couple of days later I got an idea. A wizard can make a block, or using the same power make armor that is half as effective. So can we use that armor offensively, creating a lower level, longer lasting penalty to another's actions? What do you think?
