Union-Donations no longer serve any real purpose other than for newer Unions which do not yet have all four Union-Guardians all at Max Rank 5. A time used to exist when Union-Donations were part of a Daily Quest but that now seems to be no longer. Please keep your Gems as you will need them to obtain S-Class Souls if you eventually manage to collect all the necessary materials (either that or have the $$$ to spend on the Grab-Bag Gachas which may speed up that process). Our Union already has all of the four currently available Guardians all at Max Rank 5.
