I'm inching closer to having to spend exp cards on Iri in order to complete all the quests. Is the item worth it? I don't plan on using Iri at all and would rather use the exp cards on my favorite servants.
Every servant needs crystallized lore to max out a skill to rank 10 so you need three per servant to fully rank all their skills. There are only a limited number of Lore in the game.
I would recommend against skipping it unless you are not interested in maxing out a lot of servants.
It is used for maxing any servant skills to 10, if you don't have it, your servant skills will stuck at 9 forever. And it's really worth it.
Imo, raising her to 2nd stage won't take too much exp cards.
It doesn't take much experience at all to level Iri to 50, and a Crystallized Lore is a far more valuable than those embers, because its non-renewable. It would be pretty silly to abandon one if you can help it imo.
Thanks! I ended up taking your advices and ascended Iri to finish up the quests thus far.
