All classes are provided with a skill library that spans in both Sword and Magic-based spheres. Classes who are focused on one sphere, like Warriors or Bladers, will have all its offensive and support skills in one sphere, while the other will be used only for common targeted magic spells and novice buffs, as well as an advanced one. Hybrid classes may use both spheres for different purposes; while Force Bladers develop only curses in advanced stages of the Magic sphere, Force Shielders possess some offensive unique arts in that sphere as well. Beyond offensive and support skills, there are also teleportation skills that all classes possess. Dashing is one that every character can use if they develop the necessary Sword sphere stage, which causes them to quickly dash a short distance and can be used in intervals to increase walking speed. Wizards have a unique teleportation skill called Blink which behaves similarly to Dash but is developed in the Magic sphere. Wizards are also the only class that can use both Dash and Blink and thus walk faster than any other class, effectively moving faster than even the rare vehicle items that exist in the game.
Special skills are unlocked at certain points during the character's growth by completing specific "ranking" quests. These skills include the Combo Mode, which allows several skills to be used in succession when the combo meter is pressed with correct timing, as well as several Battle Modes that provide temporary attribute bonuses to the character or even a special combat mode. Aura Mode is a basic empowering Battle Mode that can be later stacked with either advanced Battle Modes to further increase attributes. It is elemental in nature, although the element bears no difference in bonuses applied, altering only the visual effects of the skill. Battle Mode 1 is an advanced Aura Mode that is unique for all classes. Some Battle Modes provide special characteristics; the Wizard's BM1 increases both damage and Mana consumption, while the Force Blader's allows him to use elemental cannon-type spells as superior versions of the class's defensive buffs. The Force Shielder's BM1 counters enemy damage by reflecting part of it and the Force Archer's allows skills to affect more than one target in a way different than area of effect.
The last one, Battle Mode 2, provides not only an attribute increase but also a special combat mode unique to each class. Warriors are able to use scythes named Astral Lances for successive attacks and special finishing skills; Bladers use fast-paced Astral Claws whose finishing skill has the highest critical rate of all the classes' skills. Wizards are given special Orbs that allow him to target two enemies at the same time and simultaneously cast two skills, each targeting a different enemy. He can also target one enemy and use two skills at the same time against it. Force Bladers were initially given an Astral Charger which would charge up to three levels when using sword skills and would then shoot one to three magical beams when a magic skill was used. However, this was later changed into a fast-paced fencing combat mode with ethereal visual effects. The Force Shielder can turn its Astral Shield into a throwing Astral Blade Shield that is used akin to a boomerang. Lastly, the Force Archer turns the Astral Bow into dual Astral Guns that can target one or two enemies at once and deal fast damage for little Mana.
There are also other skills for different effects - classes with Astral weapons have one for summoning them, for example. There are skills for summoning vehicles such as the Astral Board and Astral Bike, as well as corresponding Combo Mode skills for when riding those vehicles, as well as many other tool skills such as Loot, Follow and Social skills, or emotes. There are also many upgrade skills which provide different and cumulative attribute bonuses in Health, Mana and secondary attributes.
Skills can only be purchased and learned when a certain skill rank or stage is achieved. Like levelling up, increasing skill ranks requires gaining skill experience which in turn is gained by using skills repeatedly, namely offensive skills. In previous versions of the game, Sword skills would only increase Sword experience and Magic skills would increase Magic experience. This was later changed to a common experience gain where any skill increases both spheres. The experience pool is shared by all skills, meaning that points gained can be applied in any skill of that sphere and any skill can be used to gain experience. Another change that was applied is the requirement of a "class rank" for achieving a superior skill rank. Class ranks are gained by completing ranking quests every ten character levels.
