Dynamic Detect Radius · Party Level Scaling

HOW IT WORKS

Base RadiusWhatever the enemy's assigned detect range is (default 50 ft · zone or per-enemy overrides apply)

Monster Eff. LevelCR ¼, ½, or 1 → Level 1 · CR 2 → Level 2 · CR N → Level N

Hero Level UsedAverage level of all living heroes (rounded)

Tier DifferencetierDiff = ceil( heroLevel ÷ 5 ) − ( monsterEffLevel + 4 )

Reduction TriggerReduction only starts when tierDiff ≥ 0

Step Size−20% of base per tier · always 5 tiers from trigger to 0 ft · proportional regardless of base

PLAYER EXPLANATION

As your heroes grow in power, weaker enemies sense the danger gap and become more cautious — their alert zone shrinks. A goblin that normally spots you from 50 feet will barely notice you at 10 feet by level 40, and ignores you entirely by level 45. The same reduction applies proportionally to any enemy regardless of their base radius — a dungeon guard with a 30 ft patrol zone shrinks at the same rate (−20% of base per tier). Only the most powerful monsters stay fully vigilant deep into your journey: the Young Green Dragon remains on high alert past level 55, because creatures like that never truly feel threatened. At 0 ft, the monster will not aggro unless attacked directly.

HOW IT WORKS

As your heroes grow in power, weak enemies become beneath you and stop giving meaningful XP. Your Threshold (your level ÷ 5, rounded up) marks the monster difficulty where you earn full XP. Beat monsters above your threshold and earn a bonus — the game rewards courage. Beat monsters well below it and XP fades, eventually hitting zero once they're trivially beneath your level. The floor is always 50% — no enemy is completely worthless as long as they still count.

SMART HIT % SYSTEM

D&D Hit Chances Converted to Percentages · Level Scaling

THE FORMULA

Base Hit %((Attacker Bonus + 20 − Defender AC) ÷ 20) × 100

Level Adjustment( ( (Attacker Tier) − Defender Tier ) × 3

Attacker TierHeroes: (level ÷ 5) + 1 · Enemies: CR rounded up (CR <1 = tier 1)

Defender TierHeroes: character level · Enemies: CR rounded up (CR <1 = tier 1)

Final Hit %Base % + Level Adjustment · clamped 15 – 85%

ResolutionRoll 1d100 — need to roll high · need ≥ (100 − Hit%) to hit · 96–100 always crits

AdvantageRoll 2d100 · keep the higher die

DisadvantageRoll 2d100 · keep the lower die

HOW D&D HIT CHANCES BECOME PERCENTAGES

In standard D&D 5e you roll a d20, add your attack bonus, and compare to the target's AC. A +5 attack vs AC 15 means you need to roll 10 or higher — that's 11 winning faces out of 20, or 55%. The Smart Hit % formula captures this exactly: (AtkBonus + 20 − AC) ÷ 20 × 100. The "20" in the formula is the d20; the numerator counts how many faces on that die would hit. Every +1 attack bonus gained or −1 AC on the target shifts your hit chance by exactly 5% — the same as flipping one extra face on a d20. Instead of rolling a d20, the game rolls a d100 and resolves it as a percentage directly, giving smoother results.

HOW LEVEL DIFFERENCES FACTOR IN

The base formula alone treats a Level 1 hero and a Level 50 hero identically — only attack bonus and AC matter. The level adjustment closes that gap. Every 5 character levels a hero gains equals one power tier — so level 1 is tier 1.2, level 5 is tier 2, level 10 is tier 3, and so on. Enemies have a fixed tier equal to their CR rounded up, with a minimum of 1 — so a goblin (CR ¼) is tier 1, an ogre (CR 2) is tier 2, a troll (CR 5) is tier 5. For each tier you outclass your target you gain +3% to hit; for each tier they outclass you, you lose 3%. A Level 5 Barbarian (tier 2) fighting a goblin (tier 1) outclasses it by 1 tier — +3% to hit. A Level 20 Barbarian (tier 5) gets a +12% bonus against that same goblin; a goblin attacking a Level 20 Barbarian is crushed to the 15% floor. The clamp ensures no one is completely helpless (15%) and no one is infallible (85%) — even the most one-sided fights have meaningful dice.
