Lore

Rydr was a young, good-willed nobleman when he was thrown into a prison, located in a place far harsher than the Icewrack Plains. A place, where evil seeped into seemingly everywhere.Rydr, still retaining his purity, made the best of his time and befriended the prisoners, who like him, wrongly held for crimes they did not commit. To the point where some 5 words would break a fight.
On one unfaithful day, Ryder woke up in the middle of a lab, arms and legs, strapped to a steel bed. Strewn with assortments of gadgetry and experiments. To be experimented on by the labs inhabitants, in hopes of creating the perfect weapon, capable of eliminating multiple targets, and slipping away with time to spare. One that could cause confusion and anger within the enemy, by disgusing as one of them. One, that could end entire civilizations in mere seconds...
The experiment brought extreme pain in Rydr's entire body, emanating from all areas, as if they would completely disintegrate at any moment. But this, in turn, gave him supernatural-like powers; extreme strength, extreme flexibility, the ability to wield nearly any weapon, and most importantly, the ability to bend light around his body, essentialy turning him invisible. On the day of his presentation to the emperor, the men found his cell wide open, with the guards lying dead on the floor, killed by an unseen force.
To this day, Rydr roams the realm, hoping to one day free his fellow prisoners from doom.

Abilities

Light Bend
Rydr reflects light around his body, turning him invisible. For every 30 seconds he stays invisible, bonus damage and attribute drain is added to his next attack, attacking a marked hero will do even more bonus damage.
Duration (Minutes) - 15/30/45/60
Bonus Damage added per 30 seconds - 30/40/50/60
Attribute Drain added per 30 seconds - 4/6/8/10
Bonus Damage to Marked heroes - 45/45/45/75
Mana Cost - 50/75/100/125
Cooldown (Seconds) - 10/12/14/16
Only a series of footsteps are heard as the Assassin strikes.



Assassin's Mark
Places a mark on the target enemy hero. If killed while marked, all of the target's hero portraits will not change (death timer does not appear as well) the death message will not appear, and Rydr will assume the appearance of the enemy hero. If Rydr attacks, or the marked enemy hero respawns, he will be revealed. If upgraded by Aghanim's Scepter, causes regular attacks to mark enemy heroes but with a 85% duration reduction.
Duration (Seconds) - 30/45/60/75
Mana Cost - 75/100/125/150
Cooldown (Seconds) - 30/35/40/45
Rydr can only laugh as war breaks out amongst the enemy.



Intangibility
Rydr's body becomes near-intangible, giving him a chance to pass through spells targeting him, affecting the closest enemy unit behind him instead. If upgraded with Aghanim's Scepter, changes Intangibility into an 800 unit aura.
Chance - 40%/50%/60%/70%
Fighting a ghost poses quite the challenge.



Clear Sky (Ultimate Ability)
Rydr dashes forward, attacking all nearby enemies in a straight line, becoming invisible soon afterwards. Applies the current level of Assassin's Mark on every attacked enemy. Creeps are instantly killed.
Dash Length (Units) - 1400/1600/1800
Fade Delay (Seconds) 1.5/1/0.5
Mana Cost - 100/150/200
Cooldown - 45/60/75
The same technique used in escaping the prison.
