End of Summer Weeks

As many were expecting, this is a 21-day Light event, and like recent events, we have the chapter of "Conquer the Guardians". There is a marathon which lasts throughout the 21 days whereby the final top 500 get the event mythic card.

Essence
The event features three types of Essence : Sun, Nature and Arcane Essence.

Sun Essence - obtained from opening duel chests, defeating guardians in event chapter, purchase using gems, or quests which opens in phase 2.

Nature Essence - obtained from defeating bosses in event chapter, or picking in a Sun Coffer

Arcane Essence - obtained from winning the event daily tournament (top 50 with most Summer Emblems each day), or picking in a Nature Coffer.

Coffers
Sun coffer - 3 pickings, 1 unique event card and Nature Essence instead of cards are guaranteed. Unfortunately, you may be forced to choose between Nature Essence and a unique event card.

Nature coffer - 5 pickings, 1 unique event card and Arcane Essence instead of cards are guaranteed. Likewise, you may be forced to choose between Arcane Essence and a unique event card.

Arcane coffer - 10 pickings, many unique event cards and artifact are guaranteed. Likewise, you may be forced to choose between Artefact dups and a unique event card.

Event Cards
These cards can only be obtained by opening the appropriate coffers during the event.

Artifact
Obtained from the Arcane Coffer, duplicates of the same artifact are combined to level it up, then inserted into any white card (without an ability). Assuming you have enough dupes, it is possible to upgrade an artifact during the next week (when it's no longer available), or even after the event ends, exactly like card seducing :

Phase 1 artifact : Blazing Rage (5-10-15-20-30%).

Phase 2 artifact : Blazing Shield (15-20-25-30-40%).

Phase 3 artifact : Blazing Cure (10-20-30-40-50%).

Conquer the Guardians
All guardians have the "disadvantageous" event color (Black for this event), and defeating them consumes energy, earns Sun Essence and Boss Keys. Defeating bosses consumes Boss Keys, earns Nature Essence and energy. You can either raid the past 2 stages you have defeated, or the next highest one which you have not defeated (you cannot raid other stages).

Combat takes into account the total damage that your cards make against an enemy with thousands of HP. You may have repeated attempts at each stage before a countdown timer runs out, after which, the HP of the chapter is restored to full. There are 27 stages in phase 1, 30 in phase 2, and 23 in phase 3 :

Path
Starting from phase 2, you can earn Sun Essence and Summer Emblems by completing Path quests. Completed objectives will not reset at the end of the daily tournament. There is a X5 inflation for Sun and Arcane coffers, and only X3 for Nature coffer :
