Missing Interludes Release Dates

Not all Interludes are available upon a Servant's release. The table below summarizes what Interludes are missing from current Servants, as well as estimated time of release based the Japanese Server.

Note: Strengthening Quests are not yet available on NA Server. They're basically Interludes but without the story, and they're numbered separately. The first batch should see release around March of 2018.
