Togis are materials used for Artifacts. Different Togis give different effects. The different effects are known once you unlock a Togi node with Artifact Energy. Different Togis are good for different situations. Fallen Angels are supposed to boost your Food Souls' stats. They are obtained from the Catacombs. Fallen Angels can have different attributes. The best ones are Cautious (Increases HP. Only useful for Tanks), Brave (Raises Attack Points. Good for DPS), and Resolute (Raises Attack Speed. Useful for Healers and DPS). You should only use Purple FAs ideally, unless you are low level. There are also different stat levels. You can change the stats using Spirit Reincarnators under the Smelt tab when clicking on a Fallen Angel. NEVER invest in a Ume Enhanced or Tsuchigomo on anything other then Resolute. Another thing to note is that you should only open As for most Fallen Angels. Ume Enhanced and Tsuchigomo are an exception because they have a higher chance of hatching then A embryos. You can also enhance a Fallen Angel at ascension +10. I only recommend this for Ume Enhanced and Tsuchigomos. As for the Fallen Angel pairings, when you click on a Food Soul. you should see a Fallen Angel tab. Click on that tab and you will be a special tab. Click on that and you should see the pairs. It will tell you a Food Souls pairing. Hope this helps! Ask any other questions if you have them.
Yeah, this happens a lot. Idk if you can get it refunded, but try to open the game again or contact Elex.
Black Tea and Milk is good. I would recommend not using Coffee and Long Bao. As you're level 81, those units should have been abandoned a long time ago. They are only for early game. I would recommend Miso if you have no SRs. If you do have SRs, I recommend using Sanma and/or Red Wine. I would also use Vodka and Pineapple Bun if you have them. Make sure they are 3* though or at least invest in them in the future. B-52 and Vodka link will be useful until late game. CLB is good, but doesn't reach his full potential until 3 stars. I prefer Tom Yum. Do not use Uke Enchanced and Tsuchigomo for anything other then Resolute. You will need them later. Invest in Braves for now. 1 Cautious and 1 Resolute is also good.
You're right. Excuse my misinformation. Although technically, Rice is one of the best, if not the best buffer in the game 5 stars.
Milk is the best F2P healer. Her link skill with Black Tea should be able to last you till mid-game. Sweet Tofu is the best permanent healer based on healing, but he is harder to ascend. After that Nagashi Somen, Candy Cane, and Nato are the best, but they are event exclusive. Fondant Cake is another healer worth investing in because she has Charm Immunity for her artifact. I think the best healer in the game is definitely SP Rice, but since she is so P2W, the best healer is Candy Cane. Getting 5 stars is doable and with a good artifact, she can dish out massive heals. All 3 are really good though. I would focus on Milk first and then switch her out for Sweet Tofu once 3 star. If you get 3 star out of one of the three then you can put them in.
