Both games open every run with a choice made before the first fight — and both opening screens are fully enumerated in the clients, down to the dice that roll them.

StS1: one whale, one dice roll

Neow's blessing menu is fully enumerated: 19 reward types across 4 offer categories, 5 drawbacks (activation bodies captured verbatim), and per-reward exclusion lists so mutually exclusive blessings never co-offer. Rarity inside a category is one coin-flip: a one-in-three roll lands Uncommon, else Common. The whole screen runs on its own freshly-seeded dice, separate from every run stream — Neow doesn't touch anything else.

StS2: the whale became a pantheon

One NPC became eight Ancients, one per act slot: NEOW, DARV, OROBAS, PAEL, TANX, TEZCATARA, NONUPEIPE, VAKUU — each bound to an act slot by hard edges (GloryNONUPEIPE). Each Ancient offers from its own relic pool (102 edges total), and the pools are uneven by design: NEOW's offers 28 relics while most others offer 10–11 — the sequel kept its whale as the widest gate.

The ascension ladder reaches into this screen too: A2 turns the Ancient heal from full into 80% of missing HP, and the epoch/timeline plane grants the Silent's unlock through Neow's reveal.

StS1 prices blessings in drawbacks; StS2 prices them in pool breadth — which Ancient you meet decides how wide your opening was.
