So testing this one out.

5 minute recast
30 second duration

This was disappointing. But when I tested it out on the Sand Sweepers in Abys-Altep it seemed like a respectably high parry rate. 3 times in a row with the JA up. Although it may be attributed to the capped parrying they give you. I also had a very high parry rate against Tablilla. I haven't had a lot of situations available to test out the enmity bonus.

Tested again, without shadows or blinding tablilla (I was being cautious the first time) the entire duration of the job ability I parried every single attack it threw at me. It wore off before it used a TP move though.
