Fields

k_armor: f64

DR knob for armor mitigation K/(armor+K). Env: OVERLORD_BAL_K_ARMOR.

k_dodge: f64

DR knob for dodge/evasion ev/(ev+K). Env: OVERLORD_BAL_K_DODGE.

power_norm: f64

Power-scalar normaliser. Env: OVERLORD_BAL_POWER_NORM.

enemy_curve_anchor_chapter: i64

Last hand-made campaign chapter (formula curve starts above it). Env: OVERLORD_BAL_ENEMY_ANCHOR_CHAPTER.

enemy_curve_anchor_power: f64

Enemy power at the anchor chapter. Env: OVERLORD_BAL_ENEMY_ANCHOR_POWER.

chapter_power_step: f64

Enemy power geometric step per chapter — the progression gate. Env: OVERLORD_BAL_ENEMY_STEP.

enemy_step_late: f64

Late-game enemy step floor. Past enemy_step_taper_start the per-chapter step decays smoothly from chapter_power_step toward this value, so the difficulty gate tracks the player’s DECELERATING late power growth (~1.12×/ch) instead of staying at the early 1.30 — which out-paced late power and produced multi-day chapter stalls / a hard wall. With >= chapter_power_step the taper is OFF (closed-form, unchanged). Env: OVERLORD_BAL_ENEMY_STEP_LATE.

enemy_step_taper_start: i64

Chapter at which the late-step taper begins. Env: OVERLORD_BAL_ENEMY_STEP_TAPER_START.

sell_price_exp: f64

Item sale-price exponent on eff (income growth shape). Env: OVERLORD_BAL_SELL_EXP.

sell_price_coef: f64

Item sale-price coefficient. Env: OVERLORD_BAL_SELL_COEF.

class_counter_swing: f64

Soft 3-cycle class-counter swing (PvP). Env: OVERLORD_BAL_CLASS_SWING.

regen_tick_max_pct: f64

Max per-tick combat regen heal as a fraction of max HP — bounds regen in combat (the scalar bound is separate) so high regen can’t out-heal all damage / instant-full a tank. Env: OVERLORD_BAL_REGEN_TICK_PCT.

hot_tick_max_pct: f64

Max per-tick HoT heal as a fraction of max HP. Env: OVERLORD_BAL_HOT_TICK_PCT.

dot_tick_max_pct: f64

Max per-tick DoT damage as a fraction of max HP. Env: OVERLORD_BAL_DOT_TICK_PCT.

enemy_early_bump: f64

Early-game stat-check bump strength applied at ch3 (tapering ch4/ch5), so the first gear conversions are forced. ch2 is left untouched (it is resource-capped by the 20 starter cookies — a bump there DEADLOCKS, sim- confirmed). 1.0 = off. Env: OVERLORD_BAL_ENEMY_EARLY_BUMP.

enemy_mid_bump: f64

Mid-game boss-only bump applied at ch7–15 to enforce the gear-engagement gate. Applied exclusively to CampaignBossFight in enemy_power_scalar; wave fights are unaffected so the global enemy_power_for_chapter curve stays monotone. At 8.0: a frozen player (stopped at ch5, power ~2121) faces P/E ≈ 0.34 at the ch7 boss → ~7% first-try win rate; combined with stop_on_lose=true on bosses and the lazy bot not retrying, this creates the hard wall. Engaged players open more chests between attempts and eventually clear the boss. Tapers to 1.0 at ch16 (one past ability-slot unlock at ch15). 1.0 = off. Env: OVERLORD_BAL_ENEMY_MID_BUMP.

eff_a1: f64

eff_by_level early-branch (L ≤ 130) coefficient. Env: OVERLORD_BAL_EFF_A1.

eff_b1: f64

eff_by_level early-branch exponent — THE early-power shape knob (lower = flatter early growth, decouples power from level/clock). Env: OVERLORD_BAL_EFF_B1.

eff_a2: f64

eff_by_level late-branch (L > 130) coefficient. Env: OVERLORD_BAL_EFF_A2.

eff_b2: f64

eff_by_level late-branch exponent (raise above 0.1 so late power keeps growing instead of plateauing). Env: OVERLORD_BAL_EFF_B2.

eff_c2: f64

eff_by_level late-branch offset (re-fit for continuity at L=130). Env: OVERLORD_BAL_EFF_C2.

Implementations

impl BalanceTuning

pub fn from_env() -> Self

Defaults, with any OVERLORD_BAL_* env var that parses applied on top. This is the sim-sweep entry point — no recompile, no deploy.

Trait Implementations

impl Clone for BalanceTuning

fn clone(&self) -> BalanceTuning

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BalanceTuning

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for BalanceTuning

fn eq(&self, other: &BalanceTuning) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
