Riah gains 35% bonus movement speed while no nearby enemy champion has sight of him. This bonus lingers for 2 seconds upon being seen.
From The Darkness functions similar to Evelynn's Shadow Walk: he will not lose the bonus due to minions or wards; only if he is near an enemy champion who can see him. While Swallow The Sun is active, the bonus is always active.
COST: 60 mana
COOLDOWN: 10 / 9 / 8 / 7 / 6
Active: Riah takes a bite out of the target enemy, dealing magic damage. If Thirst scores the killing blow, Riah heals for a percentage of their maximum health. The percentage is always 30% against minions and monsters.
Heal: 10 / 15 / 20 / 25 / 30% of target's maximum health
COST: 50 / 55 / 60 / 65 / 70 mana
COOLDOWN: 15 / 14 / 13 / 12 / 11
Active: Riah blasts the target enemy with false visions, corrupting their judgement. For the next few seconds, his target will follow Riah around and attack Riah's attack target (gaining the ability to target its allies). The duration is always 5 seconds if Riah targets a minion or monster.
Corrupted units deal physical damage equal to a percentage of their base attack damage. Dragon, Baron Nashor and Vilemaw cannot be targeted by Corruption.
Riah's basic attacks against a corrupted enemy will reduce the duration of the effect by 1 second.
Duration: 1.5 / 1.75 / 2 / 2.25 / 2.5 seconds
Physical Damage: 100 / 125 / 150 / 175 / 200% of target's base attack damage
Corruption is a form of crowd control, similar to taunt. It is affected by crowd control reduction, will be negated by Black Shield and can be removed by Cleanse and other similar effects.
Riah's "slave" has massively increased base movement speed and will share any bonus movement speed that Riah has (behaving like Elise's Spiderlings). Riah's slave cannot damage itself should Riah target his slave. The slave's allies (including towers) cannot target the slave.
COST: 80 mana
COOLDOWN: 15 / 14 / 13 / 12 / 11
Active: Riah hurls an ethereal chain at the target enemy champion, dealing physical damage pulling them half of the distance toward Riah; leaving them immobilized for a further 0.5 seconds.
Active: Riah surrounds himself in darkness, gaining health and the bonus movement speed of From The Darkness for 15 seconds. For the duration, Riah deals magic damage to nearby enemies. Enemies damaged by the shadows lose their shared vision and their sight radius decreases by 50 with each second of damage. This effect expires after 4 seconds of not taking damage.
Bonus Health: 300 / 450 / 600
Magic Damage: 37 / 59 / 81 (+ 12% AD)
Maximum Damage: 555 / 885 / 1215 (+ 180% AD)
Sight Radius after 15 seconds: 450 (normally 1200)
Fetter - Active: Riah damages and slows nearby enemies by 35% for 1.5 seconds, and applies a stacking mark for 6 seconds. At 5 stacks the mark is consumed and the target is knocked down, dealing physical damage and stunning them for 1 second.
Fetter - Active: Riah slows the target's movement speed by 35% for 5 seconds. If the target moves over 900 units while slowed they are knocked down, dealing physical damage and stunning them for 1.5 seconds.
Swallow the Sun - Active: Riah surrounds himself in darkness, gaining health and the bonus movement speed of From The Darkness for 15 seconds. For the duration, enemies within the shroud do not share their vision with their allies; and enemies outside the shroud cannot see into it.
Riah is based on the Egyptian gods: Set and Apep. He's the god of darkness and chaos, his totemic animal being the snake (occasionally dragon).
