Economy & Forge Coffer

• Tax rate — 2% of every market transaction is collected as tax.
• Tax destination — Tax gold flows into the Forge Coffer instead of being deleted. This funds the item sink.
• Purpose — Controls inflation by removing excess gold from the economy while simultaneously removing excess items.

The Forge Coffer is an automated system that purchases and destroys sink-eligible items from the market:

• Auto-buy — When a sell offer is created for a sink-eligible item, the Coffer may instantly purchase it. The seller gets gold immediately; the item is destroyed.
• Sink-eligible items — Configured in the item_sink_config table. Includes Forge Relics (IDs 32001-32009), T5+ equipment, and boss uniques.
• Daily quotas — Each item has a daily purchase quota to prevent over-sinking.
• Lore — "The Forge of Binding's Resonance Fund" — Ironhold's Smiths absorb excess magical power from the world.

• market_trades table — Tracks all completed market trades for price computation.
• Price API — GET /api/market/price/:item_id returns the computed market price for an item.
• Coffer stats — GET /api/economy/coffer returns Forge Coffer balance, items sunk, and daily quota status.

Sink	How Gold is Removed
Market tax (2%)	Flows to Forge Coffer → used to buy & destroy items
NPC shop purchases	Gold spent at NPC shops is removed from circulation
Travel costs	Gold spent on boat travel is removed
Blessings	Gold spent on blessings is removed
Warden Token shop	Gold spent at Warden shops is removed
Forge relic use	Relics consumed on use (item sink, not gold sink)
Sustained hunting costs	Mana pots, runes, food, imbuements, equipment wear (see below)

Hunting consumes resources beyond health potions. These sustained costs scale with monster tier and player level, keeping gold scarce at low-mid levels (break-even until Lv300) and allowing profit at endgame (Lv500+).

Cost Components

Component	Formula	Applies To	Notes
Mana potions	(kills / kills_per_mana) * pot_price	All vocations	Casters burn more mana (1 pot per 5-15 kills); melee less (1 per 20-40)
Runes	kills * runes_per_kill * tier * 15g	Arcanist, Verdant (Lv50+)	0.2 runes/kill for casters; melee uses none. Low-level casters use wands instead
Food	max(tier * 30, level_comp * 10) g/hr	All vocations	6 meals per hour. Higher-tier food costs more
Imbuements	max(tier * 25, level_comp * 15) g/hr	Lv100+ only	Renew every 20h. Cost = tier * 500g / 20h
Equipment wear	max(tier * 20, level_comp * wear_mult) g/hr	All vocations	Heavy armor (Guardian=30) costs more than robes (Arcanist=15)

Level Scaling (Hard Cap at Lv300)

Costs scale with level_comp = min(level, 300). This means costs grow with level until Lv300, then freeze. Since higher-tier monsters drop progressively more gold, freezing costs at Lv300 creates natural profit above Lv300.

Vocation Differences

Vocation	Kills/Mana Pot (Lv1)	Kills/Mana Pot (Lv300+)	Runes/Kill	Wear Mult
Guardian	40	20	0.0	30
Sentinel	25	10	0.05	25
Ascetic	20	7	0.10	20
Arcanist	15	5	0.20	15
Verdant	15	5	0.20	15

Mana Potion Prices by Tier

Tier	Potion	Price
T1-T4	Mana Potion	50g
T5-T7	Strong Mana Potion	80g
T8+	Great Mana Potion	120g

Economy Balance Targets

The per-kill model targets break-even (net 0 gold/hr) from Lv1-300, with increasing profit at Lv500+. This prevents gold seller spam at low levels while rewarding endgame progression.

Level	Target Net Gold/hr	Status
Lv 1	-500 to 2,000	Break-even
Lv 8	-2,000 to 2,000	Break-even (deaths expected)
Lv 20-50	-2,000 to 8,000	Small profit
Lv 100-300	-2,000 to 10,000	Break-even
Lv 500	0 to 20,000	Profit
Lv 600	2,000 to 25,000	Profit
