Aion 2 Essence Extraction (gathering)

Essence Extraction is Aion 2's gathering skill. It collects ore, gems, logs, herbs, cooking ingredients and Odyle from nodes across Atreia, and those materials feed crafting. Gathering unlocks at level 45, and mastery runs in two grades of 50 levels each; moving up a grade is a quest that asks you to extract a Splendent Ruby.

In the game's words

You can obtain various kinds of gathered materials across the fields of Atreia.
Gathered materials include [Ore], [Gem], [Log], [Herb], [Cooking Ingredient], and [Odyle].
They are basic materials for crafting weapons, armor, consumables, and more.

The Splendent Ruby quest

The quest that upgrades Essence Extraction is "[Upgrade] Essence Extraction Specialty Skill". Its journal has you extract Ruby to obtain a Splendent Ruby and take it to the Artisan Essence Extractor — Korius for Elyos, Alzirr for Asmodians — who upgrades the skill to Professional Essence Extractor. Splendent Ruby also appears in crafted gear names (the Splendent Ruby Necklace line), which is why it is the material people search for.

Materials people ask about

Raw Leather — a crafting material dropped by monsters, not gathered; its item page lists which monsters drop it.
Spiritstone — a crafting material dropped by monsters, distinct from the Resurrection Spiritstone consumable.
Odyle — gathered from Odyle nodes and used across crafting and Substance Morph.
