Revision history: Blue Archive

Blue Archive is a free-to-play squad RPG developed by Nexon Games in South Korea. Yostar published the Japanese version on February 4, 2021, and Nexon launched the global version on November 8, 2021. [1] A Steam PC client for the global version arrived on July 4, 2025. [3]

Its gacha is one of the simplest among major games, which makes it a common teaching example for spark mechanics.

Pull system

Main article: Recruitment

Pulls are called recruitment and characters are students. Published numbers: [2]

Parameter	Value
Base 3-star rate	3% per recruit
Featured student rate	typically 0.7% within the 3%
Fes banners	3-star rate doubled to 6% during anniversary periods
Cost per recruit	120 Pyroxene (1,200 for a 10-pull)

The 3% base rate has applied since July 2022, when it was raised permanently from the launch value of 2.5%. [2]

There is no rate escalation and no hard pity. Instead, every recruit grants one recruitment point, and 200 points can be exchanged for the banner's featured student, so 200 pulls (24,000 Pyroxene) is a strict ceiling. Points are per banner and expire when it ends, with no carry-over. [2]

Duplicates

Duplicate students convert into Eligma, used to raise a student's star grade. The exchange ceiling makes targeted duplicate hunting more predictable than in games with uncapped systems; see dupe system.

Service status

Main article: Release history

The game is in active service as of July 2026. The Japanese version passed its fifth anniversary in February 2026, and the global version its 4.5-year mark, each with the usual 6% Fes banner. No structural gacha changes have been identified since the 2022 rate increase.
