So I only have about 1100 mana prism and This ce is going away soon but I can only get 1 since I don’t farm prism. Is one copy worth it? If not I would prefer to keep my prism.
I would say yes, get at least one copy. Because in the future the CE will go back on the store, but if you have don’t any copies, you will have to “unlock” them by spending a Rare Mana Prism, which you can only get by burning an SR/SSR servant. So if you want to get the rest in the future (though a ways out), spend now and save later.
I could be wrong but I’m pretty sure you have to spend rare prisms regardless of whether you own one copy or not.
As I understand it, you will have to spend 1 RP to unlock it in the future store, regardless of whether you bought any this go around. So the only way to save the 1 RP is to buy them all now.
2% isn't much except for the really high bond points quests. Heroic portrait with flat 50 points will usually yield more than the 2%.
I might save up for next fall when it comes back to the rare shop and buy all 5. And it is 1 rare prism to unlock the ability to purchase all remaining copies for 1000 normal prisms each without a time limit.
Personally, I don't think that 5k MP is worth the grind for just 10%. Multiply that by 5 or 10, and I'd think differently. I don't see myself grinding out that many MPs.
