How to get Gameplay Effect Magnitude before applying Effect?

[L.F.A]

Please refer to the previous thread in this forum, ‘dynamic cooldowns’

Gameplay Ability System - dynamic cooldowns

Hello, We’ve implemented the GAS in our game with basic cooldowns; each GA has a GE_cooldown with a fixed cooldown value. How could we make it so the cooldowns are dynamic ? IE: the cooldown for a fireball ability is 10 seconds, if the player activates a “boost” the next fireball would have a 20% cooldown reduction, so would be 8 seconds. One way we could do this would be with ability level table but I don’t think this would be flexible enough for us. Thanks
