Progression Guide

Each instance of Eureka has a number of quests which you must complete in order to progress through the instance, unlock Aetherytes and (in later instances) the kettle and additional logos functionality. 
== General Information ==
There are some very useful base resources for helping progression within Eureka.
=== Trackers ===
==== Instance and Weather Trackers ====
The Eureka Tracker is a very useful tracker site, which generally has all tracking information you would require. This includes, for each instance, all of the quest locations, fate locations (and spawning mobs), and the current and upcoming weather. It can also be used to track which fates have spawned and when, and has the ability to be shared with others so that everyone in an instance can keep track of progression there. It also has a section for Logograms and a Baldesion Arsenal visual guide.
For simply tracking the weather, it is possible to use Eorzea Weather.
==== Collection Tracker ====
Ash's Eureka Collection Tracker allows you keep track of your Eurekan relic collection. It contains all of requirements for creating weapons and armour in Eureka, as well as logograms, and lets you track where you are and how far you have to go with each stage of each relic. You need to make a copy of the document prior to filling in your own data though.
All credit for the creation of this tracker goes to Ash Vaelis from the Behemoth server.
=== Useful Tips ===
==== Potion of Harmony ====
A Potion of Harmony provides you with a 10% elemental experience bonus. This lasts for one hour if NQ, or 90 minutes if HQ. In order to obtain these, you can buy them on the market board, or you can craft them as a level 60 alchemist. The materials required to craft these can be gathered from Pagos onwards, or alternatively can also be bought on the market board.
==== Eurekan Elementals ====
Every instance has three Eurekan Elementals (generally known as fairies) located randomly around the map. Upon standing next to a fairy, it will provide you with a 60 minute experience and damage up buff, as well as a regen. Each fairy has a limited number of charges it can give out, and so can be "spent" and disappear. In this case, after a short time period it will appear at another random location on the map. 
Fairies can also be killed if a mob AoE hits them, so be careful not to pull any mobs near the fairy if you're trying to take the buff.
==== Food and Potions ====
As usual, food buffs will help you with vitality and survivability. 
The potion of choice to use within Eureka is the Eurekan Potion. This will give you a 40 second long regen on a 45 second cooldown which massively helps survivability. They can be obtained from lockboxes, or from the Eurekan Provisioner NPC located at the base for 300 gil each.
