I'm thinking of getting the Advanced Summoner Bundle 4 for a price of 3000 units. It contains 6 Tier 5 CC Crystals, 1 6* Nexus Crystal, 50 Tier 2 Primordial Dust, and 1 million gold. Do you think it would be worth it as part of future prep for Necropolis or would it be better to save the units for the Banquet Event?
