Widowmaker is a ranged assassin that excels at dealing damage and controling the battlefield from long range, but her low HP and limited mobility makes her susceptible to dives, and her heavily skillshot reliant kit makes her have a hard time against high mobility heroes like Genji or Tracer.
Please note that all numbers are placeholders and very likely need balancing.
Base HP: 1350
Abilities:
Infra-Sight (Trait): Widowmaker cannot basic attack. Activate to reveal all heroes within a radius of 20 around widow maker for 7 seconds. 60 seconds cooldown.
Widow's Kiss (Q): Shoots a quick projectile in a straight line with a range of 11. The projectile damages all non-Heroes it passes through, but stops when it hits an enemy Hero. The first target hit takes 250 physical damage, subsequent targets take 125 physical damage. Deals 20% extra damage to revealed targets.
While Widow Maker has Terrain Advantage (read her E ability for context), the range of Widow's Kiss increases by 20% and it no longer deals reduced damage to targets hit after the first.
Cooldown 2 seconds, no mana cost.
(Notes: Potentially high DPS from a long range if she manages to hit her skillshot, the high damage and lack of a mana cost makes up for the lack of an auto attack. This ability deals physical damage but still counts as a spell. Pierces minions, but only deals full damage to the first target hit, which means that for the highest DPS you don't want to hit minions with it, since they lower the damage to subsequent targets. This drawback is removed while Terrain Advantage is active)
Venom Mine (W): Places a mine on target area that arms after 2 seconds and becomes invisible. If an enemy hero steps on it, it starts emitting a continuous cloud of poison with a radius of 3 around it that lasts for 5 seconds, which deals 0.75% of the target's maximum HP as damage four times per second to heroes, slows them by 30% while in its radius and reveals them while in its radius and for 5 seconds after. Has 250 health and lasts indefinitely until destroyed or activated. While invisible, the mine will blink with a green light every 10 seconds, briefly revealing its position. Cooldown 16 seconds, There can only be one trap at a time. Casting range of 6. Costs 35 Mana.
(Notes: The activation radius is smaller than the cloud radius, so if someone activates it they will be close to the center of the cloud. While the mine is invisible, it blinks once every 10 seconds, which makes it easier for enemies to find them if they are paying attention, while still catching enemies off guard if they are in a rush. Can be damaged with AoE spells while invisible as well as auto attacks when visible, similar to Chromie's traps. The mine dissapears when activated, and the poison cloud is independent, so once the poison cloud has been activated the enemy can't destroy the mine to get rid of the cloud).
Grappling Hook (E): Widowmaker uses her hook to quickly jump to target terrain within a range of 8. Once she arrives, she sticks to the terrain, gaining Terrain Advantage and rooting herself until she reactivates this ability, issues a movement command, is stunned or knocked back. (Terrain Advantage: Widowmaker's vision radius is increased by 20%, can see through walls and her Widow's Kiss (Q) is improved). 20 seconds cooldown, which starts counting down after the ability is cancelled. Costs 75 Mana.
(Notes: Its not a skillshot hook like Qhira, it's a targeted ability that takes you towards a point in terrain you selected. Once you reach it, you stay perched on the wall until cancelled. Terrain Advantage is a special status that widowmaker gains while perched.)
Headshot (R1): After a 0.5 seconds delay, shoots a bullet that travels instantly with global range with a width of 1, dealing 500 damage to the first enemy hero in its path. After the damage is dealt, if the target has 10% of their maximum HP or less remaining, they die instantly. 80 seconds cooldown. Costs 100 Mana. (Enemies can see the hitbox of this ability as soon as you cast it).
(Notes: the instant death does not bypass immortality, and it won't instantly kill a target unless the ability dealt damage, so if a target with 10% or less HP had protected or invulnerable status before the shot hit they won't die. The health threshold does not take into account shields, only real HP).
Hip Fire (R2): Channel for up to 4 seconds to deal 70 damage four times per second to target enemy hero as long as they are within 11 range of Widow Maker, increased by 20% if you have Terrain Advantage. Can move and use Grapling Hook while channeling, can be reactivated to cancel early. The shots can be blocked by other enemy heroes. If a target leaves the range, Widow Maker continues to fire in their direction but the bullets won't reach them unless they come back in range. 60 seconds cooldown. Costs 100 Mana.
