The Midsummer Fire Festival is a seasonal event that takes place during the hottest days of summer. It is similar to the Lunar Festival and other holidays, featuring some useful buffs, food, and toys to play with.
- June 21 – July 5
- Introduced in Patch 1.11
From Midsummer Fire Festival on the official website:
- Ah, so you weren't chosen for Flamekeeper this year? Don't fret, my friend! The Midsummer Fire Festival isn't merely about that traditional honor; it's a time of merriment, a chance to celebrate the hottest season of the year by lighting great fires across the land and sharing in what the elemental spirits can offer. Come to our camps and join in the revelry!
The ending of the Festival seems to have been merged with the Engineers' Explosive Extravaganza holiday:
- The lengthy Midsummer Fire Festival traditionally ends with the sky itself being set alight. The goblins of Undermine have lent their considerable skill (and copious amounts of gunpowder) to the task, resulting in a tremendous fireworks show! Take up a festival mug and raise a toast to the season as the multicolored explosions dance across the sky above you!
Overview
Touching the Ribbon Pole with another player will make you dance and yields a +30 Fire resistance buff for one hour.
- Using Ribbon Poles causes a colorful streamer of energy to go to your hand and causes you to dance. This gives a 30 Fire Resist buff for sixty minutes, but only if more than one person of the same faction is using the pole.
- When thrown into a festival fire, Burning Blossoms give you a buff
[Fire Festival Fury], 3% crit to melee and spells for sixty minutes. - Touching a fire festival bonfire will cure you of ailments, such as diseases, and also removes some buffs.
- Special flame samples can be collected from the bonfires in each of the three main cities of the opposing faction. Each sample will begin a quest called "Stealing the [City]'s Flame." Upon completing each quest, everyone in the capital city will receive
[Fire Festival Fortitude], a +30 stamina buff. Once all 3 have been collected and returned to a Festival representative, you receive the quest "A Thief's Reward" and are rewarded with the 
[Crown of the Fire Festival].
