In era, Gates of Discord Spells are obtained via a quest turn-in. There are 4 different items that be turned in. Pure Melee classes only get 2 (BER/MNK/ROG/WAR). Everyone else gets 4. The chart below shows spells/runes are needed for each class.
All turn-ins are done in Abysmal Sea via the NPC Reyfin Malakwa.
The 4 items that be turned in are:
Taelosian Geomancy Stone Eril – Drops off most Gates of Discord named (tend to be the easier zones).
Taelosian Geomancy Stone Jelki – Drops in Kod’Taz and above zones from named.
Taelosian Geomancy Stone Yiktu – Drops off most Gates of Discord named (tend to be the easier zones).
Chaos Runes – Drops from raid events Qvic, such as the Animal Event (Iqthinxa Karnkvi confirmed). Likely also drops in Inktu`Ta, and from Cynosure Kvanjji.
