Stage Gimmicks & Enemies
The event stages and challenges of this special Limited Side Story will revolve around the special Stove , Sapidity and Vapidity mechanics, with various different enemies providing different effects when defeated.
The event stages are essentially a tug of war match that requires players to convert Vapidity into Sapidity in order to best clear the stages by activating the special Stove.
Explanation of the stove mechanism
- The event maps will always have 2 kinds of Stoves: the player Stove and the enemies’ Derelic Stove.
- With each enemy defeated, they will turn into Sapidity (Red) that will gradually move towards the player’s Stove.
- If during their movements, the Sapidity’s health drops to 0, they will be turned into Vapidity (White) and start heading towards the enemy’s Derelic Stove instead.
- Players can turn Vapidity into Sapidity by decreasing their HP to 0 while they move.
- Upon either of the stove being filled up with Sapidity or Vapidity, the players or the enemy can activate the stove to summon special dragons that will fly through the battlefield, dealing true damage to all enemies or operators in their way and decreasing their resistances.
- Various enemies will have special effects that turn Sapidity into Vapidity.
- Boss of the event will have special effects when consuming a set amount of Vapidity, making it extremely important that players pay attention to these special enemies.
Therefore, players should focus on activating the Stove in order to deal big damage to the enemies on the field.

Limited Banner - Should You Pull?
Alongside the release of the special Limited Side Story Such Is the Joy Of Our Reunion, a special limited Rate Up banner will also be accompany the event to mark the 5.5 Anniversary of Arknights, featuring 2 brand new 6* Operators:
The 6* Limited Defender Operator Yu and the 6* Caster Operator Blaze The Igniting Spark (or Blaze Alter).
Limited 6* Operator Yu
Yu is an extremely powerful defender operator that has the ability to enable the special elemental damage type - Burn. His class and talent allows him to block large amounts of enemies, dealing burning elemental damage to all enemies he blocks and have amazing skills that enable other operators.
Skills:
- 2nd skill allows him to teleport enemies to his point to deal massive amounts of Burn elemental damage.
- 3rd skill (most important skill) set up a burning threshold on the field and any arts damage going past the threshold will be able to inflict additional burn elemental damage to enemies, allowing him to turn almost all arts DPS operators into burn elemental damage DPS and massively boost their damage output.
6* Operator Blaze The Igniting Spark
Blaze the Igniting Spark or Blaze alter is a Primal Caster operator that operates on Burn Elemental damage, with the ability to clear large waves of enemies. She focuses on using her different skills to set up Burning zones on the field, allowing her to inflict the Burn Elemental Damage on enemies whenever she attacks them. Depending on which skill you use, Blaze Alter will specialize in dealing with a single enemy or large group of enemies.
Among 6* Operators, Blaze Alter’s Talents are among the most interesting effects ever in the game. Her First talent allows Blaze Alter to deal a big instance of damage whenever an enemy is inflicted fully with the Burn Elemental Effect, helping to boost her damage. Her 2nd talent triggers when Blaze Alter is defeated by an enemy, granting her a massive shield buff and for short period of time, she will not retreat but will regenerate her HP every second until she regains all of her HP and become active again on the field, making her an immortal operator on the field as long as her shield isn’t broken by enemies.
Should You Pull
The answer is definite. This is one of the Limited banners coming up in Arknights and Yu is one of the best operators in the game in terms of utility, so rolling for him is extremely crucial as he is a limited operator.
Additionally, Blaze Alter works amazingly with Yu enabling her damage, so getting both of them in the team together will allow you to play the Burn Elemental team to the fullest.
