I've been looking into these three pearls lately and I've noticed something, Weaken and Fatigue are completely useless in comparison to Deter.
Here are the descriptions of the pearls:
As we can see from the description, this reduces the opponents damage by a significant amount for two rounds. Keeping in mind that this only has effect on players and not boatyard mobs.
As we can see from the description, this reduces the amount of physical the opponent can use by a significant amount.
As we can see from the description, this prevents the opponent from using any kind of buff at all for two rounds(besides teleport) making it better than the other two.
Shouldn't every pearl have its own unique advantage? Where is the advantage of Weaken and Fatigue when Deter can do the same yet a better job.
Please correct me if I'm wrong, but from what I see, Weaken and Fatigue are completely useless pearls when you have a pearl like Deter and I can't see any advantages which they may have over deter. So I'm either assuming the dev's made some sort of mistake with these pearls, or they just got lazy when it came to Weaken and Fatigue and didn't think it through properly.
