2 6 star crystals or a 6 star nexus?
I started playing mcoc again pretty late and since I was a cavalier I saw that summer of pain was going on and I did the 4 weeks that have just gone by. However i have 5k 6 star shards and the milestone im on rn is the 15k shards but if i defeat ghost I get a 6 star nexus. So that means this boss fight is the deciding factor on whether I got a 6 star nexus or 2 6 star crystals to open.
Should I go for the nexus or stick with 2 6 stars or the 6 star nexus?
