What to do with anima objects you collect on character/alts BEFORE they reach Level 60Note that you can store Anima you happen to gain (from quest rewards, etc.) in the Anima Reservoir in your Covenant Sanctum even before you reach level 60. Right-click on the NPC at the Anima Reservoir and then click on the "Deposit" button and the anima will be stored in the reservoir. I am looking forward to spending some of the anima without having to go out questing in order to do my first upgrade to the transport system. OFC, the alt I did this on was using the Threads of Fate alternate levelling method where you choose your covenant in Oribos during the early stages of the process.;)
There's a con you're not mentioning. You're going to miss out on appearance collections if you don't level at least one character of each armor type via the normal method.
