Plan pulls without pretending the server is known.

Compare the stored banner definitions, calculate independent-pull chances, and keep live pools, pity, and guarantee enforcement clearly outside the result.

Start here

01
Choose a client banner
Compare the stored banner definitions and the grade weights attached to each one.
02
Set your pull target
Pick a grade, pull count, and target chance in the probability calculator.
03
Read the boundary
Treat the result as independent-pull math—not proof of live pools, pity, or guarantees.

Calculated from client weights

What each pull can contain

Rates are each grade's summed weight divided by the selected pool's full weight. They are derived, not a server rate disclosure.

200 is client context—not proof of live enforcement

Both banner rows contain GuaranteeCount = 200. The calculator deliberately does not force a success at pull 200: active pools, carry-over rules, guarantee targets, account counters, and enforcement are server-authoritative. Client dates are table values, not a claim that either banner is live.
