Winter Wyvern/Guide

General

 * Unlike most other intelligence supports, Winter Wyvern possesses respectable strength growth, making her quite resistant to damage. However, her poor base agility also means that she has low base armor, and can benefit greatly from purchasing items that provide her with bonus armor.
 * Winter Wyvern has extreme cast range for all of her abilities, allowing her to impact ganks and team fights from the back lines without endangering herself. Purchasing mobility items allows her to position herself for casting her spells more easily.
 * Winter Wyvern has poor base movement speed and a slow turn rate, making her quite sluggish. She also has short attack range and slow projectile speed, as well as poor base damage, making her physical attacks quite ineffective at harassing when not boosted by Arctic Burn.
 * She needs good positioning and planning to make good use of her abilities. Therefore, buying mobility items helps her positioning better to use abilities or escape death.
 * Much of Winter Wyvern's damage output comes from her basic abilities, which are costly but have low cooldowns. So, securing a reliable source of mana regeneration allows Winter Wyvern to keep on the move and enter teamfights ready to use her full arsenal at all times.


 * Arctic Burn gives Winter Wyvern flying movement while boosting her attack range and night vision, as well as causing her attacks to burn a fraction of enemies' current health every second.
 * Prioritizing Arctic Burn may help make Winter Wyvern far more mobile and better able to counter enemy actions.
 * Reducing the cooldown and mana cost allows Winter Wyvern to have Arctic Burn ready as the situation requires, and helps keep her mana pool full for using other abilities.
 * Furthermore, the increased slow can help get kills during ganks, and inhibit enemy movement during team fights.
 * In the laning stage, take advantage of Arctic Burn's increased attack range, damage over time, and movement speed slow to harass the enemies away from the creep waves.
 * Use Arctic Burn at the start of team fights to slow and burn enemy heroes.
 * Arctic Burn deals damage based on a percentage of the target's current health, meaning it deals more damage the more HP the target has.
 * Use Arctic Burn to evade enemy ganks by flying over impassable terrain, preventing them from easily pursuing.
 * When initiating for a gank or team fight, Winter Wyvern can soar over trees and ledges/cliffs, attacking the enemy from unexpected directions.
 * When fighting, use Arctic Burn's unobstructed movement to keep Winter Wyvern among trees and high in the cliffs so enemies cannot reach her, increasing her survivability. As a result, she can keep using her long ranged abilities from safety.
 * Arctic Burn's flying movement, high attack range, and increased night vision range make Winter Wyvern a formidable nighttime ganker.
 * She can spot enemies from far away, allowing her to choose an advantageous approach angle with her flying movement.
 * She can attack from outside most enemies' vision range, perhaps putting their on cooldown for at least 8 seconds.
 * Winter Wyvern still possesses ground vision with Arctic Burn so she cannot see up high ground or through trees.
 * If going up high ground, try to take a side approach from an unexpected angle, using trees for cover as necessary, rather than directly up a stairway where enemies could be waiting.
 * Arctic Burn does not stack nor refresh with new attacks, therefore you should use the ability on different enemy heroes whenever possible. However, purchasing an does allow subsequent attacks to refresh the debuff.


 * Splinter Blast fires a shard of ice at a target, splintering upon impact, and damaging and slowing all other nearby enemies.
 * Splinter Blast does not affect the primary target at all, i.e. not dealing damage or slowing, so Winter Wyvern cannot use it against lone targets.
 * If trying to damage and slow an enemy, aim Splinter Blast at a secondary target so that the splinters will bounce to the primary target.
 * Max out Splinter Blast early in the game to nuke enemies.
 * The low cooldown and high area damage allow Winter Wyvern to clear creep waves in seconds and deal area damage in fights.
 * Maximum level Splinter Blast can kill ranged lane creeps in a single cast, giving her strong pushing and counter-pushing capability.
 * In the early game, use Splinter Blast on ranged creeps to harass the enemy when they are trying to get last hits. If you are using it on melee creeps, enemies may see the projectile incoming and move out of the way.
 * If creep positioning permits, try to target Splinter Blast on a siege creep, as their 80% magic resistance makes the secondary damage ineffective against them anyways.
 * However, the siege creeps usually sit well behind the rest of a creep wave, meaning that unless the melee creeps are aggroed and brought closer, a Splinter Blast targeted on a siege creep will likely only hit the ranged creeps.
 * Splinter Blast allows Winter Wyvern to hit enemies up to 1700 range away, keeping Winter Wyvern far away from dangerous fights.
 * Splinter Blast's initial projectile has a fixed 1 second travel time beyond 650 range, and cannot be disjointed, so it can always catch enemies.
 * Furthermore, the secondary splinters that damage and slow enemies in an area cannot be disjointed either once locked on, allowing Winter Wyvern to splash damage at enemies in many situations where other damage nukes cannot.
 * Because of its long range and low cooldown, Splinter Blast is good for breaking an enemy's.
 * In particular, it can clear the way to use Winter's Curse, and come off cooldown shortly after the taunt.


 * Cold Embrace disables a target ally but nullifies incoming physical damage and heals a sizable fraction of their health.
 * As a percentage-based heal, Cold Embrace will not heal much in the early game when heroes have lower health pools.
 * However, a value point in Cold Embrace still grants physical damage immunity, perhaps good enough to save Winter Wyvern and allies from ganks.
 * Cold Embrace's physical damage negation may save a teammate who has been caught out of position and is being focused down by enemy attacks.
 * When the enemies are disabling an ally, use Cold Embrace to not only heal and negate physical damage, but wastes the enemy's disabling time as well.
 * Cold Embrace does not protect from secondary attack effects, magical, and pure damage. Consider the following examples that explore the weakness of Cold Embrace.
 * keeps stealing attributes.
 * keeps destroying mana—but deals no damage—priming for dangerous magical.
 * and still deal their magical and pure damage components, respectively.
 * and deal huge magical or pure damage to finish off Cold Embrace targets.
 * can be used well with Cold Embrace as it blocks magical damage while leaving the target still able to receive other buffs such as, and so on.
 * Put Cold Embrace on creeps to prolong pushes by wasting enemy tower's attacks, allowing all other allies to continue damaging it.
 * Use Cold Embrace to tank.
 * Misusing Cold Embrace on allies in key moments in team fights will disable them, rendering them useless to contribute important abilities and attacks.
 * A good time to use Cold Embrace is when Winter's Curse is disabling the enemies, as your allies cannot damage them anyway.
 * Combining the physical damage protection of Cold Embrace with strong magic resistance from other sources such as will greatly heighten the target's chance of survivability.


 * Winter's Curse fully disables an enemy and applies a taunt to their nearby allies, causing them to attack the target with increased attack speed.
 * Winter's Curse allows Winter Wyvern to turn the enemy's power against themselves, forcing their farmed hard carries to use their powerful physical damage output against their own team.
 * In particular, enemy auras and powerful damage and attack speed buffs (such as, , and ) can cause then to connive in their own destruction by turning such abilities into liabilities should they ever clump up.
 * Winter's Curse will lock down the target through spell immunity and cannot be removed by strong dispels.
 * If an enemy carry activates, Winter Wyvern can still disable them and force their allies to attack them, wasting the enemy's spell immunity while dealing damage to them.
 * Winter's Curse cannot taunt enemies that are spell immune, so they will not attack their allies if they activate spell immunity prior to Winter's Curse. Depending on the situation, try to lock down the spell immune enemy over adjacent teammates.
 * Try to exploit its long cast range and prioritize it on a key enemy that has powerful teamfight abilities or powerful utility items.
 * If possible, use it on a squishy enemy who is standing next to their farmed hard carry to increase the odds of getting a kill. Even if a kill cannot be secured, delaying a key enemy from participating in a fight for a short duration can make the difference between victory and defeat.
 * All affected enemies will take no damage from Winter Wyvern or her team for the duration of Winter's Curse, so do not waste abilities or attacks.
 * Instead, get into better positions during Winter's Curse, getting ready to catch survivors and clean up.
 * Winter's Curse on multiple enemies can set up for allied heroes to land their own area abilities, such as, , , , and.
 * The taunt still applies to anything passing through the radius after Winter's Curse has been used, whether nearby enemies or the disabled target itself.
 * If the target is facing the right direction, try to use on them in order to push them within proximity of their allies and bring more units within the radius of the taunt.
 * Many passive abilities do not work against allied units, so do not expect enemy Phantom Assassin to inflict strikes on her teammates.
 * Examples of common effects which do not trigger on allies: most attack modifiers (critical strike, cleave, and all active attack modifiers),, , , and.
 * Examples of effects which do react on allies: all damage block, all sources of damage negation and reduction,, , , ,.
 * In the case of abilities like or, the reflected damage or passive Quill Sprays do not hit allies, but enemies still. The only exception is , which damages allies.
 * All bashes, excluding and, works on allies. Examples include , ,.
 * Some item attack modifiers also work against allies. Examples include,.
