After the quest to make Soul Lanterns and capture monstergirls, you can build a monsterhall on the overview map. You can enter this monsterhall at the sleeping chambers on the left side. The maid Vivian will be there and give you the recipe to craft various element equipment.
I've built monster quarters and captured all monsters from CG pages, except some from the challenge dungeon. Vivian is at her position in the monster quarters but i don't have any water recipes, neither when crafting nor books in key item (PS i do have water katana recipe, but not the water shield, or anything else water related). Any idea what am i missing?
