Full-mastery choices and saved openings

While all eight current skills are 99, an accepted opening rolls rarity once, then offers three bundles from three different skill themes, chosen uniformly. Pick exactly one bundle. You do not choose rarity and the rarity odds do not improve.

Each theme has a 37.5% chance of being offered among three choices. Final rewards depend on your choice, so that is an offer chance, not a fixed delivery chance.

The opening saves its current levels, Q, rarity, catalog and exact outcomes when accepted. Closing the menu, reconnecting or restarting preserves those same offers; it does not reroll them. Inventory fullness must preserve pending delivery.

Prestige distinction: a mastery opening already accepted keeps its saved choices after reset. An unopened banked key opened after reset uses your new levels and ordinary single-reward rules. Reach eight 99s again to regain mastery choice for new openings.

One opening consumes one matching key and grants one reward. Saved keys have no expiry, but their age does not lock in an earlier reward pool.
