Hmm.  Based on the math that Zaer helped me work out earlier, I believe Aramis's score on the test of spirit is 13 rounds, and that he falls to fear, rather than despair.  Though I imagine it would be easy to justify having recent events give him a small circumstance penalty on his saves vs the despair effect, causing him to fail one round earlier than normal, if you'd rather not have to do a slight rewrite on your post.
