Hello. I need some advice regarding on how I should prioritize on investing time and currency for power_stones and armor tokens for key characters which can help clear content much easier. I am even mulling the idea of selling my legacy 15CP MLB weapons for power_stones. In recent weeks, I had only truly progressed into event content with Aerith event (reached a few milestones with Armor Token rewards), but had decided against pushing for completion/mastery of later events for Lion and Auron. Latest Garnet event netted me all top prizes on-banner, but now I'm lacking the materials to max it out in order to contribute to event Co-Op proper. Furthermore, my power orbs and guard orbs stock are also at an all-time low. So I do recognize the opportunity cost of spending materials on a single character's gear in the short term, then slowly moving onto spending same materials on another character and so forth, in the long term. Fortunately, with my current stash of 30k gems and 60+ cycle keys, I certainly would look forward to pulling on upcoming banners, but it does add-on to my current situation of too many underdeveloped characters. TL;DR Please Advise on how I should proceed. Thank you. List of gear is as follows. Bolded Red highlights 35CP weapons. Bolded Blue highlights character with more than 1 Weapon and Character Armor (CA) Standard Blue notes character with only 1 Weapon and CA Weapons: Bartz 15CP MLB L35/35 Yuffie 15CP MLB L35/35 Yang 15CP MLB L35/35 Terra 35CP MLB L35/35(Previous 15CP MLB fed into this) Seymour 15CP MLB L18/35 Shantoto 15CP LB3/4 L22/30 Garnet 15CP LB3/4LB4/4 L22/30 Steiner 15CP LB3/4 L22/30 Vaan 15CP LB2/4 L24/25 Yuna 15CP LB2/4 L24/25 Edge 15CP LB2/4 L23/25 WoL 15CP LB2/4 L22/25 Ramza 35CP LB2/4 L20/25 Firion 15CP LB2/4 L14/25 Zell 15CP LB2/4 L06/25 Aerith 35CP LB1/4 L35/20 Cloud(Organix) 15CP LB1/4 L19/20 Cloud(Crimson Edge) 15CP LB1/4 L15/20 Cloud 35CP LB1/4 L01/20 Squall(Twin Lance) 15CP LB1/4 L19/20 Setzer 15CP LB1/4 L19/20 Ramza 15CP LB1/4 L16/20 Penelo 15CP LB1/4 L14/20 Wakka 15CP LB1/4 L01/20 Garnet 35CP LB1/4 L01/20 4* Shadow Shuriken MLB L30/30 Armors: Vaan Character Armor MLB L35/35 Squall CA LB2/4 L25/25 Setzer CA LB3/4 L25/25 Aerith CA LB3/4 L25/25 Terra CA LB3/4 L24/25 (Currently holding 3/5 tokens and planning to purchase another) Balthier CA LB3/4 L24/25 Vanille CA LB3/4 L24/25 Tidus CA LB3/4 L11/25 Eiko CA LB3/4 L11/25 Lion CA LB3/4 L06/25 Ramza CA LB3/4 L20/20 Garnet CA LB3/4 L18/20 Seymour CA LB3/4 L01/20 Auron CA LB3/4 L01/20 4* Cloud Shinra Beta MLB L30/30 4* Terra Jeweled Ring MLB L30/30 EDIT: After initial advice from @Cloud 616 , I had sold my old three 15CP MLBs, and spent 4 on Garnet 15CP to quickly master it and move onto her 35CP. List above revised to reflect this change.
