How do you get stella's core I cant find it in the capitial
Dark perputa is really weak against aphrodisiac, so take advantage of that and get ton of manticore spikes from the manticore, keep spamming it till you defeat her but you still need a pretty high amount of spirits(I had 10 or 9 spirits before finally defeating her) and how to get to the lake just defeat dark perputa and let the story progress perputa will give you a badge on here the lake is.
