Unique Variant
From SpiralKnights
When crafting an item, there is a low probability that you may get between one and three randomized unique variants, a special version of that item with an added bonus. You cannot choose the unique variants you obtain. When upgrading the item the unique variants can be transferred to the new item. "Unique variant" is commonly abbreviated as UV.
These bonuses appear apart from, and are not affected by, other bonuses that come with the original item. They do stack with other bonuses following the rules in abilities. Up to 3 UVs are possible per item.

Crafting
There is a low chance of creating a unique variant each time that you craft a new item. Pre-made items purchased from vendors will never come with a unique bonus.
When crafting or upgrading, unless an existing unique variant bonus is explicitly transferred to a new item (as described below), each step in the item creation process provides a new chance at a new unique variant. For example, a unique variant may appear when initially crafting a cutter, as well as when the cutter is upgraded into a striker. For items with long crafting chains, this may provide as many as five chances at obtaining a unique variant bonus per item.
When upgrading, it is possible to transfer an existing unique variant bonus on the base item to your upgraded item. In the upgrade menu, the option to transfer the unique variant bonus to your upgraded item is pre-selected. If you de-select this option when upgrading, the resultant item will not retain the existing unique variant bonus. It will, however, have a chance at becoming a new unique variant, with a new unique variant bonus or nothing.

Crafting Strategy with Alchemy Paths
Due to the ability to transfer a variant through multiple steps, a relatively economical way to obtain unique variants is to mass produce the first item in a crafting chain. For example, a unique Ash of Agni (crafting cost: 800 energy) can be produced by crafting a large number of haze bombs (10 energy each) and upgrading only the haze bomb that has a unique variant.
Types of Unique Variants
Weapons
In general, weapon bonuses will make your weapon more effective. Bonuses are not equally useful for every weapon. For example, charge time reduction on the Haze Bomb line is a lot more useful than a damage bonus since such bombs are used for inflicting status rather than dealing damage.
Weapons can gain any of the bonuses listed below. These bonuses seem to be percentage based depending on the base stats of the weapons, check the Abilities for such info.
- Attack speed increase (ASI) (can't be obtained on bombs)
- Charge time reduction (CTR)
- Damage bonus vs (construct, gremlin, fiend, beast, undead or slime)
Weapon UVs come in Low, Medium, High and Very High. Weapon UVs are never Ultra or Maximum.
A total bonus of Ultra or Maximum can be obtained by combining the UV with the inherent bonus on a weapon or armor as explained in the Abilities article. For example, a Combuster UV ASI Very High will become Maximum when a Vog Cub Coat is equipped since the Vog Cub Coat has Sword ASI Medium. The Character Tab displays the combined abilities of weapon bonuses.
Armor
Armor unique variants focus on adding protection against damage or status effects. Unique variants can either add defense against attacks that the armor would not normally protect against or stack with existing defenses on the armor.
Possible types of unique variants are:
- Bonus damage protection from: (normal, piercing, elemental or shadow)
- Bonus status resistance against: (stun, freeze, sleep, poison, fire, shock or curse)
Bonus damage protection, much like base damage protection, increases with the star-rating. For example, a low elemental UV on a 4* helm could appear longer than a medium elemental UV on a 2* helm. This assumption is made based on watching the tooltip, and remains untested.
The possible UV values an armor can have are: Low, Medium, High, Maximum. There are no Armor UVs with the values of Very High or Ultra.
Shield
Shield unique variants are as with Armor.
Probability
Chance of an UV on bombs seems to be around 10% [1][2]
Probabilities on bombs seem to be approximately as follows: [3]
Low: 65.74% ± 8.95%
Medium: 21.30% ± 7.72%
High: 7.41% ± 4.94%
Very High: 5.56% ± 4.32%
Chances for armors and other kinds of weapons remain to be tested.
