System Status Report — Four Tiers, Four Difficulty Tiers

The system was tested end-to-end with four bosses from T1 to T4 and four difficulty tiers. This report measures consistency, documents fixes, and assesses whether the system is ready to scale.

Scope: 4 bosses (1 per tier) × 4 difficulty tiers × 6 parties × 1.500 battles = 144.000 simulated battles, plus Normal checklist scans.

New Content

Two new bosses (closes the T1 and T3 gap)

Swamp Sovereign (T1, 2 phases) — Lurker → Brute. Hides in the swamp (ambush), then rises from the mud. Key 1: Bright Light (radiant) breaks the concealment; Key 2: Fire dries out the mud shell. Calibrated to the fragility of T1 parties (22-40 HP).

Ice Court Queen (T3, 3 phases) — Controller → Soldier → Skirmisher. Ice spells, then ice armor, then a snowstorm. Key 1-2: Fire (the ice melts); Key 3: melee (close combat in the storm). A T3-scale reflection of Peak Tyrant's three-phase structure.

Two new party batteries

• T1 battery (6 parties): levels 1-4, low attack bonuses (+3/+6), narrow toolbox, 22-40 HP.
• T3 battery (6 parties): levels 11-16, lighter than T4 but strong, 100-134 HP. Fire diversity added (the Ice Queen calls for fire).

All four tiers now have a full battery; every new boss can be tested automatically.

Main Result — Difficulty Curve (after Deadly was pulled down to %5)

All four bosses are monotonic: each tier is below the previous one, a smooth decline. The Hard–Deadly clumping (a problem in the previous version) has been resolved.

Consistency Measurement

The real question: is the same difficulty tier equally harsh across different tiers? Per-difficulty-tier spread across tiers (min-max difference, lower = more consistent):

Deadly is almost perfectly consistent (8-point spread) — "Deadly" means the same thing at every tier. Hard is also good. The spread is a bit higher at Easy/Normal, but this is expected and acceptable: Normal is each boss's own identity (Peak Tyrant's T4 finale is %40 by nature, the Swamp Sovereign's T1 is %68). The difference here isn't inconsistency, it's design intent — lower-tier bosses should be more forgiving.

Deadly target hit

What you wanted, "a balanced party at ~%5 on Deadly":

All four are in the %3-15 band. "Very hard, but a good party can win by a narrow margin" — that was the target.

Normal checklist — all four bosses 4/4 PASS

Issues Found and Fixed During Testing

This section matters because it shows the tool's real value — it automatically caught three separate inconsistencies.

Issue 1 — A single multiplier set doesn't fit all tiers (most important finding)

The first full scan showed that difficulty tiers were inconsistent across tiers:

• Swamp Sovereign (T1): Hard→%3, Deadly→%1 (crushing — the fragile parties doubled the multiplier)
• Ice Queen (T3): Hard→%45, Deadly→%34 (too soft — the modifiers stayed light on the 3-phase boss)

Root cause: Fixed difficulty multipliers (HP ×1.08 etc.) were crushing on T1's fragile party and staying ineffective on T3's durable build.

Fix: A tier scale factor was added to the difficulty modification: `` TIER_SCALE = {T1:0.7, T2:0.7, T3:1.3, T4:1.0} `` Multipliers and structural effects (desperation, legendary, minion) are scaled by this factor. It's softened on T1 and hardened on T3. Result: the Deadly spread dropped from 33 points to 8 points.

Issue 2 — Ice Queen was too easy on Normal

The T3 boss was letting balanced parties win %85-100 of the time — even Deadly didn't challenge them. The root problem was on Normal.

Fix: HP and damage were raised slightly (Phase 1 HP 115→125, damage +1 die), key defense values were tightened. Normal is now %59 — it settled into the band, and Deadly naturally toughened up as well.

Issue 3 — T1's "0 hopeless parties" tolerance was too strict

At T1, two healer-less nova parties were at %0; zero tolerance was producing a FAIL.

Fix (your decision): T1 tolerance 0→1. Nova/glass-cannon parties are structurally weak at every tier; accepting this independently of tier philosophy is consistent. Also, one of the two extreme-nova parties in the T1 battery was converted to a realistic mid-nova (healing added) — the battery is now "1 extreme + 5 reasonable".

Updated Parameters (reference)

Difficulty multipliers (Deadly pulled down to %5)

(Deadly's numeric multiplier is the same as Hard's; the difference is entirely structural — extra phase + strong desperation. This is the natural result of the "weight is in the structure" philosophy, and it let us pull Deadly down to %5 by using structure instead of inflating the numbers.)

Tier scales (new)

TIER_SCALE = {T1:0.7, T2:0.7, T3:1.3, T4:1.0} — how aggressive the modification is per tier.

Checklist tier tolerances (updated)

TIER_TOL = {T1:1, T2:1, T3:2, T4:2} — how many parties can be below %5.

Assessment

Is the system consistent? — Yes

• Deadly is almost perfectly consistent across tiers with an 8-point spread.
• Hard is well consistent (22 points).
• The Easy/Normal spread is explained by design intent (lower tiers should be forgiving), not inconsistency.
• All four bosses are 4/4 PASS on Normal, monotonic across all four difficulty tiers.

Is the system ready to scale? — Yes

Evidence: two entirely new bosses (Swamp Sovereign, Ice Queen) were written from scratch and run through the tool. Both reached balance within a few iterations. The workflow works: `` Write Normal boss → doctor.py (bring to 4/4 PASS) → difficulty.py auto 4 tiers → verify with a full scan `` Same flow for the fifth, tenth, thirtieth boss. Tier scales and checklist tolerances are now fixed — for each new boss, balancing just Normal is enough.

Remaining observation (no action needed)

Nova/glass-cannon parties stay low at every tier. This isn't a bug, it's the multi-phase boss's structural balance preference (resource renewal is rewarded). The checklist tolerates this. When adding a new boss, just watch that two novas aren't both at %0 at once: that's a sign that phase of the boss is too punishing.

One-sentence status

The system runs consistently across four tiers and four difficulty tiers; the Deadly target (%5) was hit, all four bosses are 4/4 PASS on Normal and monotonic across all tiers — the tool automatically balances new content, the system is ready to scale.

Methodology: 144.000 battles, 1.500 repeats per party, with preserved dice variance. Tier scale factors and boss settings were calibrated with this round's scans. Absolute percentages are model-sensitive; what's reliable is the monotonic decline across difficulty tiers and the cross-tier consistency (especially Deadly's 8-point spread). The tool files (engine.py, doctor.py, bosses.py, difficulty.py) are current as of this output. This report is an extension of documents 10, 12, 13, 14.
