Skills are temporary effects activated by their icons.
Whenever there's (skill) written after the description of a skill, it means that that particular skill is an active one. Meaning there's a hotkey assigned to it in which you have to click in order to benefit from it's effects. There's a duration and cooldown timers tied to each of these skills.
Important: Some skills bear the name, noted in parentheses, of upgrades, but these are not related and are assumed to be misnaming from the developers.
