Blue Archive 50/50 Explained β€” Winning, Losing, and Guarantees

How the 50/50 works

On a limited character banner in Blue Archive, every 5β˜… has a 50% chance to be the featured character and 50% to be a standard-banner character. When you lose, the next 5β˜… on that banner type is guaranteed to be featured β€” this is called the guarantee, or "倧保底" in Chinese communities.

Strategy around it

The math

Across many pulls, about 75% of players get their target within 180 pulls (90 + 90 worst case). Budgeting 160-180 pulls for a must-have character removes most of the variance from your plan.
