50% is a very good offer. You should all get some Gems if you're having trouble collecting them in-game. At the very least you can use them to buy some Pure Hybrids from the DBM for Battles and for Breeding, best of all if you don't need DBM Dragons and save them for buyout of Quests in case you're just short of completion.

Don't go crazy though. xD
