Ascending difficulty
Optional difficulty tiers the player unlocks and stacks after winning — Slay the Spire's Ascension levels, Hades's Heat — each adding modifiers that make runs harder in exchange for prestige or rewards. Designers use ascending difficulty to extend a roguelike's life indefinitely for skilled players: the base game teaches the systems, and the ascension ladder is the real long-tail challenge, self-paced so players climb only as fast as their mastery allows. It also solves the 'game got easy' problem without punishing newcomers. Key decisions: whether modifiers are fixed per tier (a clear ladder) or player-selected (Hades's à-la-carte Heat lets players tune their own challenge), reward coupling (do higher tiers pay out more, or is bragging rights enough?), and pacing the difficulty curve so each step feels surmountable. Pitfall: modifiers that add tedium rather than challenge — more enemy HP is a slog, smarter enemies are a test.
