Unfortunately, I didn't test it for display, as the hero had more skills and abilities than normal, in addition to the ones listed above.

Well, in that case, everything can only be found out through test battles. I don't know how the game handles a larger number of skills. Perhaps it's normal, meaning the game has a limit on the number of skills gained when leveling up, or perhaps there is no limit. Then, 6 skills and 19 perks would be the maximum; the game might crash or not read the extra perks.
