Easy way to get all Disciplines
Create 1 character of a certain class (example Monk)
Go to Vs. Battles & have rounds set to 1
Have the Character fight them self (Monk vs. Monk) with health set to 10%
The number of battles to do is
13 Discipline 2
25 Discipline 3
38 Soul of Discipline 1
50 Soul of Discipline 2
Can I do that with 2 characters at once?
Yes, same procedure except it's create 2 characters of differing jobs that don't have all disciplines & the count is 25, 50, 75, 100
What if I don't have a second controller?
Quick play set to 1 round, though the number of fights you have to do is equal to doing the above (25, 50, 75 ,100)
For Chronicles of the Sword the levels to unlock disciplines are
Lv.10 Discipline 2
Lv.20 Discipline 3
Lv.30 Soul of Disciplines
Another way to get the Disciplines is to play through Survival (Hard) once, Survival (Normal) twice or Survival (Easy) 3 times and 10 battles on the next run through (Brought to you by Jukain)
By play through that means fully finish
