How to Beat Friend or Foe

Hand the Red Eye to the Old God and you buy a special sermon — and keep the ending at its standard bar. Keep the Red Eye and you renovate the attic at home into the Old God's lodging, and all six townsfolk raise their Final Battle requirement from 90 reputation to 100. The keep path adds extra requests on top — the Elegant Prosthetic among them. Pride, itemized.

The standard bar — 90 reputation per townsfolk — already requires every character quest in the game: each pays +10, and all 51 land the six at exactly 90 alongside the 41 main quests. The 100 bar means the same ledger plus the extra requests, with zero slack left over. This is the one quest where the completionist surcharge is printed on the menu. Budget accordingly.

• Hand it over: a special sermon, and the ending stays at 90 reputation per townsfolk.
• Keep it: an attic tenant at home — and a 100 reputation bar for all six, plus extra requests like the Elegant Prosthetic.
• Check your quest ledger before deciding: the 90 bar has no slack, so the 100 bar is strictly more game.
• Either way The Ancient One pops — the achievement does not price the choice, the ledger does.

After the choice, the road to The Last Battle is pure ledger work: character quests until the six townsfolk hit their bar, main quests until the story is current. The Sewers themselves still need clearing on the way down — the Sewer Brawl and the sewer battles are part of the approach. Walk out with the decision made and the math already done. Regret is a poor potion ingredient.
