Well after throwing in some spare 4* toons and dupes and achieving an exalted sacrifice and filling the purple ring, I gotta say I'm a little bummed out. I was cursed with the 2 skill shard reward from the sacrifice and the ring bonus awarded me with 4 more skill shards and 10 rare GA souls. And said souls yielded one 4* golden son and nothing else... I think I'm done with this event lol. I like the skill shards, I have 8 now counting the two I had before the sacrifices and I'll probably use those on my new eternity soul I'll have this week (fingers crossed for no second Beelzebub) but it did take kind of a while to get those souls. Oh well, those toons weren't exactly A+ fighters. I suppose that after all of this, I agree with some of the people who were talking about this.
2 skill shards is a dreadful reward for an exalted sacrifice.
