Can you return to a god that you defected from eventually. I'm worshiping Kumiromi so I could get the scythe (It seems to be the best weapon a fairy can use) but now that I have it I want to get some more treasures for me and god weapons for my pets. That said without Kumiromi it is kinda pointless having a farm. So I can return to him once I get what I want, right?
Yep, at any time. When leaving a god, you lose any "Faith points" you've accumulated and get hit with a 10,000 turn curse; but otherwise there's nothing else.
Welp, I stole the kitty bank from Noyel (10k) and I am currently saving up for... Something.
Question, should I get a Ranch, Farm or Museum?
Depends, the ranch is useless without the ability to catch monsters, and the museum is useless without statues/cards. Ranches can make decent amounts of money and corpses for stats, but the museum can make bank with little player interaction aside from placing statues/cards.
Putits can easily be caught with a domination rod and any level of magic device, breed quickly, and give charisma when eaten; where the museum is easily maxed out with lots of Gwen the Innocent statues/cards.
