Loot & Rewards

Overview

• The BossRush Mod loot system follows different rules depending on the mode. This page details the loot mechanics for each mode.

Standard BossRush Loot

Random Loot Toggle

• The config option enableRandomBossLoot (default: on) controls whether the BossRush random loot system is active.
• When disabled, BossRush no longer takes over the vanilla Boss drop flow, and all quality distribution rules below do not apply.

Loot Crates

• After each Boss is killed, a loot crate spawns at its death location.
• The number of drops is determined by the Boss's health, ranging from 7 to 15 items (higher health = more drops).

Quality Distribution Modes

The config option useLegacyBossLootProbabilities controls the quality distribution algorithm. Default is true (Legacy Probability Mode).

• This setting no longer affects only Standard BossRush; it also applies to the corresponding regular loot-quality paths in From Scratch / Faction War / Blood Hunt as described below.

Legacy Probability Mode (Default)

• Each quality tier has an independent drop probability determined by a bonusFactor.
• bonusFactor = 80% × health factor + 20% × kill speed factor, range [0, 1].
  • Health factor: normalized position of the Boss's max health within the Boss pool's min–max health range.
  • Speed factor: remaining ratio of kill time relative to a reference time window (faster = higher).
• Quality probabilities scale linearly as bonusFactor goes from 0→1:
  • Quality 8: 0.05% → 0.10%
  • Quality 7: 0.10% → 1.00%
  • Quality 6: 1.00% → 5.00%
  • Quality 5: 5.00% → 10.00%
  • Quality 1-4: remaining probability split by weights 0.1345 : 0.3655 : 0.3655 : 0.1345
• Q5+ Guarantee: when the Boss's max health > 250 and the loot crate contains no quality 5+ item, one extra Q5+ item is appended (90% Q5, 9% Q6, 0.9% Q7, 0.1% Q8).

Simplified Probability Mode

• Set useLegacyBossLootProbabilities to false to switch to this mode.
• Item quality is divided into two tiers: normal (1-4) and high quality (5-8).
• Total high quality probability is affected by two additive factors:
  • Boss health bonus: +5% per 100 health points
  • Kill speed bonus: the faster the kill, the higher the bonus (up to +10%)
• Internal high quality distribution: quality 5 : 6 : 7 : 8 = 4 : 3 : 2 : 1
• No Q5+ guarantee mechanism.

Note: The main gameplay-facing differences between the two modes are the probability distribution algorithm and the Q5+ guarantee behavior. Candidate-pool filtering details can also differ between the two paths.

Completion Reward Crate

• After defeating all waves, the completion reward crate no longer appears instantly by the signpost.
• It now first shows up as a highlighted ghost crate above the player, then materializes and descends slowly before becoming a normal interactable reward crate:
• Easy (1 Boss/wave): 3 high quality items
• Normal (multiple Bosses/wave): 10 high quality items

Loot Blacklist

• The following types of items will not appear in the loot pool:
  • Items flagged as non-droppable
  • Demo-locked items
• Quest-tagged item handling depends on the active loot-probability path; Legacy mode applies the stricter exclusion rule
• Crown drop weight is reduced to 0.1x, lowering its appearance frequency.

Infinite Hell Rewards

Per-Wave Cash

• Each Boss kill grants cash = Boss max health × 10.
• Example: a Boss with 1000 health drops 10,000 cash on kill.
• Cash pickups within 2 meters of the player automatically fly in; outside that radius you still need to move closer.

Random High Quality Items

• Every 5 waves, 1 high-quality item drops.
• The reward pool prefers items with quality ≥ 5 and value ≥ 10,000; if no candidate meets that value threshold, it falls back to other quality ≥ 5 items.

Milestone Grand Rewards

• Every 100 waves triggers a milestone reward containing Crowns and large amounts of cash, scaling exponentially:
  • Wave 100: 1 Crown + 10,000,000 cash
  • Wave 200: 2 Crowns + 20,000,000 cash
  • Wave 300: 4 Crowns + 40,000,000 cash
  • Wave 400: 8 Crowns + 80,000,000 cash
  • And so on, doubling every 100 waves.

Early Wave Protection

• Early waves automatically exclude certain high-intensity Bosses to avoid encountering overpowered enemies at the start.
• As waves progress, the Boss pool gradually unlocks all Bosses, with difficulty steadily increasing.

From Scratch Loot

• Enemies carry random equipment, all of which drops in a loot crate on kill.
• Equipment quality increases with waves: quality = 1 + (wave/5) + (enemy health/500).
• Later enemies may drop equipment better than what you currently have.
• When useLegacyBossLootProbabilities = true, From Scratch uses the Legacy Probability Mode for the quality distribution of enemy backpack bonus items, backpack refill items, and extra backpack ammo stacks.
• This toggle does not change drop counts, equipped weapons, melee weapons, equipped gear, or the ammo currently loaded for combat.

Faction War Loot

• Killing an enemy faction's Boss drops a loot crate.
• Killing a same-faction Boss does not drop a loot crate.
• Dragon Descendant and BEAR faction promoted minions carry random equipment.
• When useLegacyBossLootProbabilities = true, regular on-death backpack loot in Faction War also switches to the Legacy Probability Mode.
• The toggle only affects backpack bonus items / backpack refill items / extra backpack ammo stacks, not the enemy's live combat loadout.

Blood Hunt Loot

• When useLegacyBossLootProbabilities = true, regular on-death backpack loot in Blood Hunt also switches to the Legacy Probability Mode.
• This only affects regular backpack loot quality. It does not affect drop counts, bounty bonus drops, extraction rewards, or any other shared high-quality reward-pool payouts.
• Killing a bounty Boss drops extra items from the shared high-quality reward pool, with the quantity equal to the number of Bounty Marks on that Boss.
• Upon successful extraction, each Bounty Mark on a player = 1 item from the shared high-quality reward pool, sent to the Storage Point.
• Both reward sources currently reuse the same shared reward-pool rules.

Custom Boss Exclusive Drops

When killing a custom Boss, in addition to the regular loot crate, exclusive equipment drops separately (independent roll, not affected by quality weights):

Dragon Descendant

• Crimson Dragon Helm (Helmet): 30% drop rate
• Flame Scale Armor (Armor): 60% drop rate
• Dragon Breath (Firearm): 10% drop rate

Skyburner Dragon Lord

• Cloud Rider (Totem): 15% drop rate
• Dragon King Crown (Helmet): 15% drop rate
• Dragon King Scale Armor (Armor): 15% drop rate
• Reverse Scale (Totem): 35% drop rate
• Skyburner Halberd (Melee): 15% drop rate
• Dragon Cannon (Firearm): 5% drop rate
