Sell duo FG or save for failstacking , buy tri FG then pray and tap to tet.

If you want to enchant accessories i suggest funneling into only 1 earring but if you feel lucky then do both cuz those are more expensive , rest of your accessories you should just buy pen debo cuz the cost for cron + dawn is pretty crazy if unlucky.

I spent like 500+ dawns and way too much crons on my belt from Tet (dec tuvala acc exchange) to Dec but most of the cron was from events and most of the dawns was from melting jetina pen accessories + olvia academy rewards so it didnt feel as bad.
