Some pirates' skills do not activate correctly, or at all. I have noticed this on Dark Night Cherron and Explorer Niera, though their problems are each a bit different.
Steps to Reproduce:
1) Brawl and have skills activate
Skill does not activate regardless of number of brawls (Dark Night Cherron), skill activates but has no noticeable effect on final damage numbers (Explorer Niera).
skills activate and affect the attack values in the brawl.
**Note: I'm not 100% on this as it is hard to test defensive skills, but Light Admiral Harpo's skill seemed to lack effect as well and could use a glance.
