The wiki states, that after one has access to all the gods (don't know if this would included the Pactmaker), there is the chance to find the subdungeons with the Crusader. Since the wiki is outdated i don't know if this information is still valid.
But in my case i got the Crusader before Tikki Tooki (and the Pactmaker) and still missing both
So i don't know if this is a bug, or the wiki is not up-to-date in this case?
And can give me somebody any hints where to find Tikki Tooki?
