Saber Stats: Nature, Class, and Wield(s) Explained
To help returning customers keep up with new releases, we have developed an efficient method of organizing our selection of sabers. This system separates sabers based on their Nature, Class, and Wield(s). We call this system Saber Stats.
The "Saber Stats" section of the Glaive product page.
Nature:
The nature of a saber is the measure of its tendency towards Light (good), Dark (evil), or Grey (balance). Whereas a a Light-natured saber will have an elegant, civilized appearance, Dark-natured sabers are often designed to look lethal, with darker hilts and sharper details. A saber's nature is often influenced by the character who wields it as well as the tendencies of its Krystal. A saber's nature is determined for aesthetic/narrative purposes, and does not affect its technology, durability, or any other physical/technical characteristics. For example, both Dark and Light colour-changing sabers feature the same selection of LED colours. 
Class:
Contrary to a saber's nature, a saber's class is very indicative of both the physical and, in some cases, technological properties of the saber. The four basic saber classes are the Vanguard, the Assassin, the Titan, and the Hybrid classes. For example, sabers belonging to the Titan class are primarily designed for two-handed combat; they are heavier, their hilts are massive, and they are often only compatible with Heavy blades. Assassin class sabers, on the other hand, are smaller, lightweight, ideal for dual-wielding, and are mostly only compatible with Light blades. To discover your ideal saber class, make sure to take our Saber Class Quiz.

Wield(s):
There are many ways to use a saber in combat. A duelist can operate a saber One-Handed or Two-Handed, and can also choose to Dual-wield. Although every saber can be operated with one hand, both hands, or in a Dual-Wield configuration, some sabers are designed for specific wields. For example, Titan class sabers are often difficult to wield one-handed due to their weight. If the Saber Stats section for a saber does not list a one-handed wield under the Wield(s) heading, chances are it will be difficult to wield it in only one hand.
Some wields require the hilt to be physically modified or accessorized, such as when adding a Cross-Guard or even linking two sabers together to make one Double-Bladed saber. If any of these options appear in the Saber Stats section under the Wield(s) heading, they are compatible with the saber. If these options do not appear in the Saber Stats section for a saber, this means they are not compatible. To accessorize your saber with a cross-guard or to get massive discounts on a second saber and a coupler for a double-bladed wield, simply look for the "Cross-Guard" and "Double-Bladed" option under the Hilt Variant field when customizing your saber.
Certain sabers will have unique accessories that only apply to that specific saber. For example, the Warblade can come with a disc-like, ringed cross-guard to protect you from strikes to your hands while dueling. However, since this accessory only applies to the Warblade, we call this kind of wield a Modified wield. Look for the modified wield symbol in the Saber Stats category to see if this applies to your saber. You'll find all the possible modified wields available under the Hilt Variant field while you customize.
