SOFT CAPS/DIMINISHING RETURNS
Stat investment yielding less past thresholds — the fortieth point of vigor granting a sliver of the tenth's health, armor percentages asymptoting, stacking the same buff at reduced effect.

Dark Souls institutionalized visible soft caps (the community's level-40/60 breakpoints are build-planning scripture), Elden Ring layers multiple cap tiers per stat, MMOs like WoW built rating-to-percentage conversions with built-in decay, MOBAs diminish stacked crowd-control durations to keep chain-stuns survivable, and idle games are diminishing returns as aesthetic. Designers curve returns because linear stacking breaks games at the extremes: without caps, optimal play is always maximal specialization (all points in damage, forever), and content must be tuned against degenerate mono-stat builds — but diminishing returns make the frontier bend, so past the soft cap the next point is worth more elsewhere, and build diversity emerges from arithmetic rather than rules. Soft caps also protect multiplayer sanity (defensive stacking that asymptotes can't reach unkillable) and give designers a gentler tool than hard caps: the door doesn't slam, it just becomes less worth walking through. The communication problem is the design's real burden — the curve is invisible, so players either learn breakpoints from wikis (externalizing the game's math) or waste resources past caps unknowingly (the respec-inducing discovery that levels 40-80 of strength did almost nothing). Key decisions: cap visibility (in-UI breakpoint markers versus community archaeology — the honest choice is increasingly standard), curve shape (stepped tiers are learnable; smooth asymptotes are fair but illegible), and which systems deserve caps at all — diminishing crowd-control is player protection, diminishing damage is build shaping, and they carry different obligations. Pitfall: caps that punish the uninformed exclusively — when breakpoints are undocumented, the mechanic functions as a tax on not reading wikis, invisible to optimizers and brutal to intuitive players; a soft cap the game won't show is balance achieved by misleading your least-informed customers.
