Sainted Pride is the first Incorruptus Soul for the White Knight. This soul is obtained right after your first fight with the Black Knight. The game will then pop-up with a tutorial on the souls. The affect will take place when it is equiped and you have Leonard transform into a level 1 or higher knight.
Notes: Transformation Lv. 1
Equipped effect: Slightly boosts the overall ability of nearby party members.
