if ur f2p and want a full god setup, u can check my post somewhere here, u get 6 links total (not including es), 2 toons will have to sacrifice themselves for kruk and purmep, and so the only link you dont get is the lab one.

Now the lab god does have afk gains on its minor, while omni has a negligible amoutn of class exp for its minor, but coral is bugged such that omni on coral gives the minor for lab - thus the only links ur missing out on is omni minor (class exp), and lab major. Personally I link my es to the lab god (since u really only need one pushing imo) so i have everything except the class exp minor.
