Hi,
Finally finish my necropolis 1st run


Got science gem and titania 7*, should I rank up her to 3? Or should I invest in odin r2 for necro exploration in future?
Should I wait next pool of titan crystal to open?
Last question is on who ascend, but I would go for kate to r5 and ascension (already have rank up material)
Thank you all and best luck with necropolis
