But you also can't get to a Goblin population above 60 with Shakala alone, they die off faster then she can birth them.
Technically you can. Gobbos dying and how many kids Shakala has are both RNG checks; the gobbo death chance increases at 30+ (and again at 60+) but the number of possible kids per goblin pregnancy doesn't increase (or go down).
The math is gnarly if you're not a statistician but unless you're consistently lucky on the RNGs it'd take 20+ Shakala pregnancies to get to 60+ and you probably won't ever get much above that. I'm not a statistician and if I'm wrong it's probably worse. Still possible, but even longer to do...
Multiple goblin wives is
definitely the way to go to trigger Obeah's appearance. Not to mention more fun.
