When you have no Discipline and thus 0% cooldown reduction bonus to your grenades, your grenade ability recharges in 1 minute.
Discipline stats do not affect cooldown until the next tier is reached.
When you have enough discipline to have 100% cooldown reduction bonus to your grenades, your grenade ability recharges in 27 seconds (45% of original recharge).
To reach 100% cooldown reduction bonus, players will need 272 points in Discipline.
- If you have more than 272 points in Discipline, the extra points are wasted.
