If you really want to get him, you should save all the crystals you can. So that you can Crystal Invoke as much as possible when he does return. Unless you are willing/able to spend a lot of money buying crystals.

You get crystals from clearing Town quests and event quests, and they are also gifted quite frequently, such as daily log-in bonus (5th/9th days), Boot Camp, gift quests (Christmas/New Year etc.).

Never ever use your crystals for anything except expanding your Spirit Limit. You can get new spirits by doing events. Even if you can only clear the 2* quests, by slowly building your team you can start to tackle 3* quests, and so on.

The three starter spirits Ignis/Sasha/Infernagg can be obtained from Friendship Invoke and are quite strong when fully evolved, so keep Encouraging to accumulate Friendship Points.

Wizard Cups (special tournaments held occasionally) also give away crystals and spirits.

TLDR: Hoard your crystals for until Dietrich returns.
