Types

Types in Eyliss are divided into five categories; Elements, Skill Types, Weapon Types, Armor Types, and Equipment Types.

Elements
There are technically 10 elements in Eyliss. 8 of them (Fire, Ice, Thunder, Water, Earth, Wind, Light, and Darkness) are used by magic spells. Physical is the element of a character's default attack, although there are weapons and armor that can change this.

The tenth element, Death, is used by instant death skills such as Perish Song and Killing Edge. While not "officially" recognized as an element on its own, boss enemies are immune to the Death element to prevent them from instant death skills that would break the boss fight.

Many enemies deal elemental damage, and may be immune, strong, or weak to certain elements (e.g. Saplings taking 150% damage from fire skills).

Skill Types
Skills in Eyliss are divided into two types - Magic and Special. Magic skills cost MP to use, while Special skills cost TP. MP can be increased and decreased like HP and is affected by MMP (Max MP), while TP is not an attribute that can be raised or lowered - instead, a character's TP is increased during battle, meaning that not even a fully healed character can use all their special skills right away.

Magic skills are mainly used by Spellblades, Shamans, Sorcerers, and Theurgists, although any character can learn magic skills through the use of Skill Cards.

Weapon Types
There are 14 weapon types in Eyliss: Dagger, Sword, Flail, Axe, Whip, Cane, Bow, Crossbow, Gun, Claw, Glove, Spear, Tome, and Chainsaw. A 15th unused and unnamed weapon type exists in game data, used for placeholder purposes. Likewise, while Glove appears as a weapon type, there are no glove weapons nor are there any classes that can use the weapon type.

Dagger is the only weapon type meant for Dual Wield use,  as the only class that can use it (Assassin) can only Dual Wield weapons.
