On the Reddit forum, a few snippets of code that relate to Seraphine abilities were accidentally leaked.
A couple of weeks ago, a Brazil streamer named Streamie revealed a series of new skin lines and potential upcoming champions including Samira and Seraphine. The new marksman, Samira, was described to be a very “jaw-dropping” while Seraphine would be a “sensational mage.” This “pinky” girl is favored by Riot to create social media accounts, posting activities such as daily life, music cover,… It’s just like a normal person.
A couple of hours ago, a Reddit account called u/adenrafael revealed the code displaying her skillset. While the validity of these details has not yet been confirmed, however, League players are looking forward to seeing this champion as well as her potential performance in Summoner’s Rift.
Passive (?): Echo
For every third basic ability cast will have Echo effect then casting it again.
Skills – Harmony
Casting an ability grants a Note to nearby allies for {0} seconds. For each Note, Seraphine’s next attack gains bonus attack range and deals additional magic damage.
Skills – Shield
Shields all nearby ally champions and grants them {3}% Movement Speed for {4} seconds. If Seraphine is already shielded, nearby allies are healed by {5}% of their missing health for each ally.
Overall, Seraphine’s abilities are expected to be a Mage-support similar to Karma or Lulu. The passive (?) may be said to be a combination of Sona’s present passive and the Mage-class feature in Teamfight Tactics. With regard to the Doublecast skill casting, it is a symbol in TFT Mage-class (Season 2 and Season 4). Whether Riot is attempting to put the mechanics of this game mode into League of Legends?
In short, this is all just reference information, her actual skillset remains a mystery to League players. Perhaps we need to hang tight until the 2021 preseason or Worlds 2020 to know exactly what Seraphine’s abilities are.
