Understand skills and build your first combat routine

Regional reference: the official Korean skill guide distinguishes mastery, passive skills, Stigma, specializations and presets, and describes four Stigma quickslots. Its dynamic content was only partially accessible. This does not independently verify every global launch detail.

Active versus passive: an active is deliberately used; a passive changes how your character or abilities behave. Read the supporting effects, not only the visible hotbar.

Chains: inspect what enables a follow-up and how long its opportunity lasts. Learn the condition for each link instead of treating all skills as interchangeable buttons.

Stigma: treat limited slots as build choices. Identify whether you need damage, control, survival or support, then check the acquisition and slot rules in your own client.

Specializations: compare the tooltip before and after selection. A choice may change behavior rather than merely increase damage. Exact rank breakpoints and point allocations are deliberately not prescribed across differing versions.

Presets: verify what a saved configuration actually stores. Equipment, skill investment and specialization choices are not necessarily the same setting.

Tooltip checklist: target; range or area; resource cost; casting or movement restriction; cooldown; trigger or chain condition; damage, healing or status effect. Then ask what would make using it now a mistake.

Suggested first session: learn movement and targeting in a low-risk fight; identify one reliable attack sequence, one emergency defensive action and your main group utility. Add complexity only when these are comfortable.

Compare two legal loadouts against the same enemy type, changing one thing at a time. Judge survival and ease of execution as well as damage. Check PvP-specific rules before copying a PvE setup.

The fan database Aion2.dev discloses Steam playtest build 25344886, extracted September 16, 2026. Its Skills section is useful for exploration, but unreleased records, unresolved effects and final launch values require in-game confirmation.
