3- Basically spells like skills that use a long charge time need that. Don't use silence before asking if the tank is stunning, or that may cause problems.

4- As far as i saw, differents song stack. I used foe requiem while another bard ballad. They both worked.

5- for stats, i suggest going full 30 dex. we got already a decent amount of mp at lvl 50, so we can sustain song as much a needed.


Hope this will help :3
