Saga

A Saga is a group of quests or even story arcs that characters can complete for an additional reward.

Introduction
When running these quests, you will receive a number of “points” towards your reward based on what difficulty you run quests on. The benefits earned are a single choice from Experience Gem (consumed automatically on acquire), Renown Gem (consumed automatically on acquire), or a selection of 1 to 4 Skill tomes, based on the total “points value” of the quests you have run. The higher the points total, the better your reward would be (and more tomes will be available to choose from).

Awarding points:
 * One point per casual/normal completion
 * Two points per hard completion
 * Three points per elite completion
 * VIP can skip one quest and count it as an elite completion (3 points)
 * Everyone can pay 5 Astral Shards to skip one quest and count it as an elite completion (3 points)
 * You can do the bypasses once per run through each saga.

Depending on the number of points you have accumulated, you receive your reward. There are four reward levels: normal, hard, elite, and true elite. For a true elite reward, you need to complete all quests on Elite difficulty (maximum points).

As your reward, you can select general experience (immediately granted), guild renown (immediately granted), and skill tomes. The number of offered skill tomes depends on your reward level; a single tome is offered for normal completion, and up to four on true elite (you can still select only one).

Two sagas were released with the Shadowfell Conspiracy expansion, and an additional seven were added with U19.2. Update 22 added the Pirates of the Thunder Sea (heroic and epic) sagas. As of U22, there are a total of 4 Heroic Sagas and 7 Epic Sagas.
