well we are now at the 3rd SERRIS 10x since iv been playing at no unkillable =(
1-2 Key UNM is only meant for special folk i guess =(
guess i will continue to 4 key UNM well into future
I would prolly expect to see Serris several more times before you see Demytha.
Block Damage and Unkillable champs are rarely the 10x champs.
I assume you didn't do the Helicath fusion? Seems you are only 6 months in, I know it was quite a while before I had the resources to do fusions, especially in the limited window I have to play. So I expect no, but would be happy to hear you got him if you did.
