OOC:
Ahem, you need to divide by 5, since you have the Weak Spontaneous Magic flaw. The roll also does not add to your casting total, it just checks for botch. So we have just your casting total, which is 10, divided by 5 gives level 2.
The spell you're trying to cast is level 25, as explained above. And you'll need to reach higher if you want penetration.
Really, I wasn't kidding about miming. You can't cast spontaneous magic, manx - that's the flaw you chose.
Let's just break the circle and be done with it, guys. We need to advance this plot already.
