I got started on this over Christmas and have been playing pretty heavily ever since. I managed to get the Slepnir monster from the tower event, and I've been working pretty ridiculously to try to get the SSS required to recruit it.
And I know that isn't going to happen. :- b
So, I estimate by tonight I'll be sitting at ~160 SSS and a level 40 Slepnir. Would you:
A) Try to recruit Slepnir
B) Likely recruit a Mermaid
C) Sell your SSS
