Loot system

Drop chance

Drop chance determines the chance to obtain something upon killing an enemy or opening a chest. You can obtain only one item per enemy or chest but this excludes gold and there is no limit for ultra rare items.

Equipment

Outside of a few exceptions, all equipment item drops from enemies and chests are randomly generated. Their item level depends purely on the enemy level or the chest level.

Rarity generation

Most of the loot sources can drop equipment of only 3 or 4 different rarities. Every enemy and other loot sources have a different drop rates but in general, you can expect drop rates based on the following table:

Table key

• Extremely high - expect 90% of cases and more
• Very high - expect 50% of cases and more
• High - about 30% of cases and more
• Moderate - 20 - 30% chance
• Low - 20% chance and less
• Very low - 10% chance and less
• Extremely low - 3% chance and less
• Almost impossible - 0.5% chance and less
• None - Items cannot drop in this rarity from this source

Possible rarities of loot and their expected drop chance

	Common	Uncommon	Rare	Epic	Legendary	Celestial
Open world
Enemies	Extremely high	Very low	Extremely low	None	None	None
Elites	High	Very high	Extremely low	None	None	None
Bosses	None	Extremely high	Very low	Almost impossible	None	None
Dungeons
Enemies	None	Extremely high	Very low	Almost impossible	None	None
Elites	None	High	Very high	Very low	Almost impossible	None
Bosses	None	None	Very high	High	Extremely low	None
Main bosses	None	None	None	Extremely high	Very low	Almost impossible

Items always start their rarity rolls from the best one avaiable first before rolling worse rarities. You can increase your chances with luck and rarity potions.

Example:

There's an item with 1% Rare chance and 9% Uncommon chance. When the item drops, it tries a rare roll first - if it hits in the 1% chance, the item will be rare, otherwise it does the same with uncommon chance. If the item fails all rarity rolls, it drops with the lowest possible rarity of it's source.

Stat generation

Item level generation

Lowest possible item level, rounded to full number = $Enemy\;or\;chest\;level*0.92$

Highest possible item level, rounded to full number = $Enemy\;or\;chest\;level*1.08$

Item generates its item level somewhere in this range, rounded to nearest full number.

Item spread

Not every equipment piece is equal. Pieces for some slots can add different amount of stats than others based on their stats spread.

Stats

Every time a new item is generated, it generates a base stat value with this formula:

$1.06^{{\text{item level}}-1}$

Base stat value example

Item level	Stat value
1	1
5	1.26247696
10	1.689478959
15	2.260903956
20	3.025599502
25	4.048934641
30	5.418387899
35	7.251025276
60	31.12046307
70	55.7320096

Secondary stats heavily depend on the item's rarity as with every better rarity tier, the item gains an additional secondary stat.

Rarity multipliers

Rarity	All Stats multiplier	Amount of secondary stats	Item value multiplier
Common	1	0	10
Uncommon	1.05	1	20
Rare	1.1	2	40
Epic	1.2	3	80
Legendary	1.35	4	160
Celestial	1.5	5	320

All stats are affected by the rarity multiplier and the base value. Percentage based stats (critical damage, haste, etc.) and armor are generated as rating.

Equipment also multiplies the result base stat value by a specific multiplier for each stat regardless of whether it's a flat value stat (Power, Vitality, etc.) or rating.

Stat multipliers

Stat	Value
Weapon attack	4
Power	30
Vitality	30
Critical chance	40
Critical damage	150
Hitpoints	25
Haste	30
Luck	100
Mana regeneration	40
Evasion	25
Cooldown rate	25
Armor	20
Havoc	40
Torment	40
Precision	40

Specific equipment pieces are also affected by stats spread.

Final stat calculation formula:
$(1.06^{{\text{item level}}-1})\times {\text{rarity multiplier}}\times {\text{stat multiplier}}\times {\text{stat spread}}$

When it comes to main stats, they can be also multiplied depending on the item type. Equipment can exist in 3 variants

• Offensive
• Balanced
• Defensive

These variants are tied to the item so you can't get the same item in multiple different variants.

Item variants multipliers

Variant	Armor multiplier	Attack multiplier	Power multiplier	Vitality multiplier
Offensive	0.7	1.15	1.15	0.7
Balanced	1	1	1	1
Defensive	1.3	0.85	0.85	1.3

Value

Item value is generated based on:

• Value spread
• Rarity multiplier
• Item level

Value spread multiplier

Equipment type	Multiplier
Weapon	0.25
Off hand	0.12
Helm	0.09
Chest	0.15
Legs	0.1
Shoes	0.06
Cloak	0.06
Gloves	0.05
Rings	0.06

The value is calculated by:

$1.13^{{\text{item level}}-1}*Spread\;multiplier*Rarity\;multiplier$
