Drop rates

Item types

When generating a random item drop, the game first chooses the type of item. The relative chance of getting each item type is given in the following table. However, a given item drop source may not allow every possible type. For weapons and armor, the tier depends on the chapter and is also given in the table.

Item type	Relative drop rate	Tier
		Chapter 1	Chapter 2	Chapter 3	Chapter 4	Chapter 5
Weapon	0.3	1	1	2	2	3
Armor	0.31	1	1	1	2	2
Augment	0.4
Off Hand	0.1

If a weapon drops, the relative odds of each type of weapon are as follows:

Weapon type	Relative drop rate
Sword	1.0
Axe	1.0
Spear	1.0
Mace	1.0
Bow	1.5
Crossbow	0.8
Dagger	0.7
Staff	1.0
Wand	0.8

If instead a piece of armor drops, the relative odds of each class are as follows:

Armor type	Relative drop rate
Warrior Armor	4.0
Hunter Armor	3.0
Mystic Armor	2.0

Artifacts

If weapon is selected to drop, there is a chance that it will be an artifact weapon. The chance starts at 0, increases by 0.15 each time a non-artifact weapon drops, and decreases by 0.5 each time an artifact weapon drops. The following artifacts can appear as random drops. Each artifact of a given type is equally likely to drop. Accordingly, the table lists each artifact's effective drop rate, which is calculated as the weapon type's relative drop rate divided by the number of droppable artifacts of that type.

Name	Type	Effective drop rate
Fatetracer	Sword	0.250
Icebreaker	Sword	0.250
Eaglewing	Sword	0.250
Baleblade	Sword	0.250
Fang Axe	Axe	0.125
Flare-axe	Axe	0.125
Lockbreaker	Axe	0.125

Wyverntail	Spear	0.200
Halehammer	Mace	0.333
Quakebaker	Mace	0.333
Titan's Fist	Mace	0.333
Antler Bow	Bow	0.500
Strongbow	Bow	0.500
Vigilkeeper	Bow	0.500
Bolt-thrower	Crossbow	0.267
Frostfang	Crossbow	0.267
Mothbite	Crossbow	0.267
Wingknife	Dagger	0.350
Wraithword Knife	Dagger	0.350
Sojourner	Staff	0.500
Winterfur Staff	Staff	0.500
Swan Scepter	Wand	0.267
Longwatch Lamp	Wand	0.267
Firling Wand	Wand	0.267

An artifact will not drop if a hero in the campaign already possesses it. This behavior can raise the effective drop rate of other artifacts of the same type.
