Seline the Aeromancer by Cuttleboss

The Aeromancer is made to be master of the positioning in the battlefield. She is a support who is packed with strong offensive spells. Her built in synergy of her skills gives her a strong ability to create a lot of chaos in teamfights. She is not for new players, as her ability to move enemies can easily put them in a better place than they were before, or misusing the spell can potentially lead to her being punished due to its long cooldown. She can be played in both safelane and offlane, since her ability to push enemies out of position (or allies back to safety if she has the shard) makes her quite versatile and powerful.
Seline is the hero you want on your team if you are ranged and your enemies are melee. Her abilities allow her to grant range and knockback, and she can protect her cores from melee heroes with Flurry Wave and can easily slow them with Wind Sabre. She is also a hero that forces enemies to initiate well or be picked apart and mispositioned by her ultimate. She is a hero who fights with her team, and as such struggles against a lot of gankers who can blow her up easily.

In order to get the best results, Seline is best if she's played aggressively, to get a lead so as her abilities to control positions is capitalized on. Her ability to control enemy positions are a lot less useful if you can't fight them anyway and if losing she would be relegated to just trying to save her allies. In a sense she plays like a Disruptor with positioning based long ranged teamfighting skills (and a way to check up cliffs for wards with Wind Sabre). She is weak to BKB and will fall off for much of the game if enemies get ahold of them. Her late game is also strong with her Scepter, since Breathstealer can function like a pseudo- Doom and pierces spell immunity.

With her strong late game talents, it is likely tempting to play her as a core, but it won't be recommended due to her lack of proper scaling damage. Her attack speed talent is more for using Gale Touch effectively than to make her into a right clicker.

Seline is a complicated and difficult hero to play. Her skills are easy to misuse and she's fragile and easy to kill. In order to play her well, she needs a lot of practice and game knowledge. As such she has a medium-high skill floor and a high skill ceiling.

For skills, Flurry Wave is almost always for the first level. It is the most generally useful of all her spells and has a lot of potential damage from the beginning of laning.

Generally max Flurry Wave or Wind Sabre first and skill them together. Which one you max first depends on whether or not you need the additional damage and slow from more Wind Sabre levels. Otherwise the longer push (for save and aggressive plays) and increased tree damage make Flurry Wave more appealing most of the time. These two together are Seline's bread and butter combo.

Gale Touch is a spell you "touch" later. It does not shine until later in the game during sieges and fights. A value point is perfectly acceptable as it offers some bonus damage for harassing and lane control. if a lane is really hard, it may be worth it to put more points in this, as it offers more damage to the carry and more range (if they are ranged). In trilanes this spell is also worth the value point as it would give a lot of overall damage.

Twister should be taken whenever possible (though be mindful there is a large mana cost increase from level 1 and level 2). The spell is very powerful for all sorts of clashes and the damage and AOE both increase each level.

Attribute Bonuses: Seline is very unlikely to put bonus points into Attributes over levels in her spells, but of all the spells to be neglected in favor of stats, it would likely be Gale Touch if she lacks the proper ranged allies to use it.


Talent Choices:

Level 10: Wind Sabre Radius vs Gale Touch Attacks. The Wind Sabre radius makes it more useful and easier to land on enemies, making it a more reliable source of damage. The Gale Touch bonus attacks are highly appreciated for long ranged right clickers, especially fast-hitting ones that need more than 6 attacks.

Level 15: Wind Sabre Stun vs Damage. A tough choice. Wind Sabre bonus damage adds quite a bit of damage to Seline's combo due to a single Wind Sabre being able to damage three times. Wind Sabre stunning allows it to disrupt enemies a lot more, especially if properly chained with Flurry and Twister.

Level 20: Attack Speed vs Global Range Gale Touch. The attack speed makes Seline's own Gale Touch a lot more useful as you can shoot all 6 (or 8) attacks very quickly and it helps with any damage or intelligence items you may have. A global range Gale Touch gives her just that, a global presence where Seline can help her allies if they're jumped on or if they are sieging even if she's on the other side of the map, which makes that talent more useful overall but less specialized.

Level 25: Twister Pierces vs Low CD Flurry Wave. Essentially on one hand Seline finally gets a counter to BKB and allows her to damage, kite and misposition heroes through all of that. On another hand, if she can actually use Flurry Wave multiple times in a fight this can highly improve her presence and make her in general less of a walking ultimate. It basically depends if your team bases you around Twister or not.

Ideal Allies:

Ranged Right Clickers:
Seline helps heroes that would benefit from Gale Touch to kite enemies. Her other skills can also help them if they get jumped on.

Tanky Frontline Heroes:
Seline can more easily manipulate the enemy's position if she has an ally that the enemy will gather around. Many of these heroes are also powerful teamfighters too.

Wall Builders:
These heroes allow Seline to easily push enemies into a wall for extra damage with her Flurry Wave.

Distance Moved Punishers:
These heroes punish people for having position forced to move. These are very useful for capitalizing on her skillset.

Good Against:

Kiteable Melee Heroes:
Heroes that do not like being blasted by Flurry Wave and Gale Touch attacks are miserable around you.

Fragile Backline Heroes:
Twister can bring these heroes into really dangerous positions in the frontline where it is very easy to kill them.

Dangerous Channeling Spells:
As Seline has Twister to interrupt channeling through Glimmer, she is able to stop these spells easily. Once she has the talent, she can use Wind Sabre as well to stop these spells. Even when they get BKB, if she gets the Twister talent, she can still stop the spells.

Spell Spammers:
Once you have Breathstealer, spell spammers will have to volunteer to not cast spells or lose mana and take huge amounts of damage.

Worst Enemies:

Global or Very Long Ranged Heroes:
Seline is a fragile backline hero that prioritizes cast range and staying back to stay safe. Heroes that have powerful global abilities are a big threat to her.

Sneaky Gankers:
Seline can be very easy to kill if you can sneak up on her, since she is fragile and may not always be able to push herself to safety.

Silencers:
Without spells, the Aeromancer is useless and very easy to kill. Also hello again Riki.

Mobile Heroes:
These heroes nullify the usefulness of a lot of her skills since they can re-position themselves very easily. You might also notice Riki again. Just note that Aeromancer is the exact type of hero he hunts.

Personality:
Aeromancer's personality is a bit like a dark version of Crystal Maiden's. She is smiling and cheerful, but a deeply traumatized young woman underneath too. She takes great pleasure in killing her enemies, especially if they are monstrous in appearance. She also speaks to the winds when she is confused or happy with herself and this makes her seem more insane. Despite this she still shows appreciation and respect to many characters and people who help her and it is easy to see that she has good motivations at heart.

Interactions with Other Heroes:
Seline is not kind to her enemies. She will often throw biting insults towards enemies she kills if the are demons like Shadow Fiend. She also have a massive amount of hate for Undying as he is the agent of the Dead God, and conversely will look forward to fighting with Anti-Mage, who she considers the only person to hate the Dead God nearly as much as her. Her hate for the undead carries over to heroes like Death Prophet, Muerta and Wraith King. She shows respect to other elemental casters like Crystal Maiden, Sand King, Lina, and the Spirits. She is annoyed by Invoker's arrogance, but respects his power. She also is annoyed with Batrider, who finds her way too crazy. She has respect for Omniknight but says that there are more paths to justice than just the Omniscience and that her time there was not well spent (Seen in the Priestess of the Omniscience set). She also have a somewhat petty relationship with Windranger, who she considers the inferior chosen one of wind, but will work with her and even compliment her.

Lore Strength, Classification, and Comparison:
Gender: Female
Age: Early 20s (The Dead God's legions destroyed her town when she was a child)
Classification: Human Mage
Powers and Abilities: Air Manipulation (control over wind, including the ability to deprive air from people, can levitate people with this power), Weather Manipulation (Can create a massive tornado instantly), Limited Elemental-lingualism (Seline can communicate with the winds of Stone Hill that follow her, but not with other elementals).
Stamina: High (Travels on her own for long periods of time, eliminating foes along the way)
Intelligence: High (Seline is a skilled Aeromancer and was the only one in her town to notice the dangerous omen, but her lack of sanity and traumatic responses make her impulsive)
Comparable Power Scales: Similar to other mages in the setting that have mastered an element but are not fused with it (vs someone like the Spirits)
Lina, Crystal Maiden, Disruptor

Voice Sample:
Based on Kirumi Tojo from Danganronpa V3, voiced by Kira Buckland. Seline speaks very properly and enunciates her words a lot. She also sounds very determined. She is also prone to outbursts of huge emotion. Play Video Warning: Video audio contains spoilers for DanganronpaV3. Do not listen past the first few minutes of the video if that concerns you.

Set ideas:
Priestess of the Omniscience


Art by SNK

Head: Hood of Purification
Rarity Rare
While seeking allies to fight the Dead God, Seline found herself following the Omniscience for a time. While they did not give her answers they did give her another hood.

Chest: Gown of Sisterhood
Rarity Mythical
Though these gowns used to be common, the Sisterhood path had become less popular in the Omniscience as many of the members die on pilgrimage to the cliffs of Emauracus.

Legs: Skirt of the Faithful
Rarity Uncommon
Every priestess was expected to wear these skirts but it proves difficult not to trip over them.

Arms: Golden Bracelets of the Omniscience
Rarity Common
These bracelets show devotion to the All Seeing One, though to Seline the Winds of Stone Hill proved more useful.


Standalone Item: Glimmering Robe
Chest: Glimmering Robe

Based on the Glimmer Cape item, it features it in an alternate style, as a robe. Has a special effect when using Glimmer Cape active on self on an ally.
An aeromancer needs to sometimes stay out of sight.
