I've seen people get non-level 30 rares during colorfest, so my guess:
Roll for godfest. If not, roll for colorfest. If not, roll normally.
Well, yeah I already know..ish... kinda disagree... Basically my motto is:
roll for godfest, don't roll for colorfest, don't roll normally...just be happy if the colorfest is the color you want DURING godfest (there's always a colorfest so it's not about the 2 being together a rare thing so much as which 2 are together).
What I meant is if there's a blue colorfest egyptian godfest, and you get an egyptian god, would the ratio be something like 19% horus, 19% anubus, 19% ra, 19% kitty, 24% Isis? or 15% horus, 15% anubus, etc? I know nobody knows EXACTLY, but I figure someone who has opened tons, or someone has seen a guide or whatever stating if the difference is at least noticeable or negligible.
