Balrog PQ and Evan masteries

Most likely 1st and 2nd only also, unless Nexon happened to have changed something especially for evans, as the map itself restricts use of only beginner, 1st job, and 2nd job skills. Passive skills such as crtiical will still work though.

I'll guess the other way, and say that everything up to around lvl 70 will be able to be used (plus all passive skills, of course). So either 5th or 6th mastery skills will be the limit.
