KMST Battle Mage Revamped Skills

The main attack uses skills from all the levels (1st job, 2nd job etc.). But you only need to press one of them and the game will auto-randomly chain for you the level skills with a shorter delay. That was what I experienced.

Like say, I use the 3rd job main attack skill. If you press it again, you can activate the 1st or 2nd job attack. They change randomly. But if you use a lower level skill (2nd job), you can only randomly get 1st or 2nd job attacks.

So I guess that explains the lesser lines, we have a Magic Thunder Breaker now.
