Active and instant abilities
See also: Spell mechanics
Abilities are divided into 2 main categories:
- Active abilities
- Instant abilities
Active abilities
These abilities can be casted only when you're not casting any other ability but they can be casted while you're moving, although doing so slows you down by 40%. The following abilities are in this category:
Instant abilities
Usage of instant abilities is limited only by their own cooldown and they can be used even while you're casting other ability. The following abilities are in this category:
Toggled abilities
Toggled abilities are Instant abilities that can be turned on / off. To do so, you can either use the ability again or as many toggled abilities create a status effect, cancel it instead.
Hidden abilities
These skills cannot be assigned. They do not affect combat and can be used only by interacting with something.
Unlocking and upgrading abilities and perks
You can unlock any ability in the game by opening the skills window ("K" by default). All abilities available to be upgraded show a plus sign inside of their icon. You can unlock or upgrade it only if you have enough combat or profession points.

After unlocking a new ability, most of them can be upgraded to level 2 and some even to level 3. Levels can unlock additional status effects the skill can apply or many other various boosts to their power.
