Shadowplay Skillset
Below you can see the skillset for the Shadowplay class in ArcheAge. There is a list of active abilities and a list of passives that you can choose between. They are locked behind a level requirement so you are unable to pick the strongest one from the start. Each skillset has its own individual level that gains XP through the typical means of questing, farming, gathering etc.
Every few levels you will be awarded a skill point that you can spend in your skill tree. You can reset your skillsets at any time by pressing the Reset Skills button at the bottom of the UI and you can also change your skillset completely by talking to a Skill Manager.
