Special 2.5 Anniversary Banner - Should You Roll

2.5 Anniversary Banner - Unstrained Liquor, Pellucid Heart

Available exclusively during the Anniversary Event period and lasts for 2 weeks only, the brand new limited banner features 2 amazing 6* rate up Operators - The 6* Supporter Ling and the 6* Specialist Lee.

The rate for this banner is the usual 2% for a 6* operator with Ling and Lee accounting for 70% of the chance when you get a 6* operator to appear when you roll in the gacha. It is important to note that among the 2 6*s available, Ling is a LIMITED TIME AVAILABLE OPERATOR, meaning once this banner ends, she will not return to the game in at least 1 year time. So it is important that you consider this factor when rolling in this special banner.

In addition, during the banner period, all players will be granted 1 single pull every day for FREE, allowing players to make up to 14 pulls during the banner availability period.


As a 6* Specialist Operator, Lee provides players with an amazing kit for utility in both his abilities and skills. Lee’s ability allows him to essentially hold 3 lanes of enemies by himself as long as you have enough DP to sustain him on the field.

Lee’s unique trait makes it so that for every 3s he stays on the field, he will consume 3 DP (2 DP if he has his module), making it extremely difficult to maintain Lee on the field if you don’t have a Vanguard. However, his utility allows him to circumvent this cost by making him essentially being able to solo 3 lanes of enemies all by himself without having to rely on others to keep him alive, making him an immensely valuable Operator to have when dealing with maps who have massive amounts of enemies.


The 6* Limited Timed Available Operator and one of the 12 Dragon siblings together with Nian and Dusk, Ling is a 6* Supporter Operator with the ability to summon special familiars to aid her in battle. Ling is the epitome of the Summoner Archetype with her ability to summon familiars with proficiency in long-ranged attacks in addition to close-ranged combat.

Ling’s 2nd skill allows her to summon Familiars that attack from a range, binding the enemies and dealing massive amounts of Arts damage to them in 1 blast. Her 3rd skill is the direct opposite, with familiars being able to be deployed for close-range combat, and merge together in order to form an impressive never seen before 4-block familiar that deals arts damage to all enemies it blocks and enemies within the 4 titles surrounding it. 

Should You Roll

Yes you should. This special 2.5 banner is perhaps one of the best banners in the history of Arknights as it provides players with 2 specially designed operators that is good for both new and veteran players. 

In addition, this banner essentially gives 24 pulls for free for all players, allowing all players to half the pity requirement to obtain a 6* operator, so at the very least, players should roll on this banner until they get 1 6* operator. Not only that, aside from the 2 rated ip Operators, the previously Limited Operators -Nian and Dusk- are also on rate up in this banner, accounting for 30% of the 6* operator rate when you get a 6* operator in this banner. Therefore, this banner is a good chance for players to try and get all 3 of the Dragon siblings available in the game as of this moment
