Nightstalker, the Hunter of the Void. Destiny Parody Idea.
In no way am I going to take credit for the concept of this post. I just really like writing down champion concepts, so I decided to take this from Destiny, and modify it to be a useable, hopefully balanced League Champion. He would be a ranged marksman/assassin, most suitable for top or mid lane. I always thought that the Nightstalker subclass would work well in League of Legends, so here it is:
Passive: Firefly Nighstalker uses his signature Hand Cannon, Ace of Spades, to attack enemies. When an enemy minion or monster is killed, they will explode, dealing 20/30/40/50%(Increases at level 5, 10, and 15) of Nighstalker's attack damage to nearby enemies. This effect increases to 100/125/150/175%(Increases at level 5, 10, and 15) if he kills a champion. Additionally, crits on enemy champions Mark them, revealing them for two seconds.
Q - Shadestep: Cost : 20/30/40/50/60 Mana Cooldown : 12/10/8/6/4 Seconds Nighstalker evades, rolling in a target direction and becoming briefly invisible. Nighstalker's next attack will crit guaranteed, dealing 150/175/200/225/250% of Nighstalker's total attack damage (affected by Infinity Edge).
W - Vortex Grenade: Cost : 70/85/100/115/130 Mana Cooldown : 10/9/8/7/6 Seconds Nighstalker tosses a grenade at a target location, dealing 30/50/70/80/90 (+20% Bonus AD)(+50% AP) physical damage every second for 2.5/3/3.5/4/4.5 seconds to enemies in it's radius.
E - Smoke: Cost : 100/110/120/130/140 Mana Cooldown : 18/16/14/12/10 Seconds Nighstalker throws a smoke bomb at his feet, stealthing himself and nearby allies for 2/2.5/3/3.5/4 seconds. Enemies within the smoke cloud are slowed by 50% and blinded while they remain within the area of effect. Nighstalker can use Shadestep without breaking stealth.
R - Shadowshot: Cost : 100 Mana Cooldown 80/70/60 Seconds Nighstalker summons a Void Bow, channeling for 1 second before firing it in a target direction. Upon hitting an enemy champion or reaching max range, after a 2 second delay, it will tether up to 5 nearby enemies (prioritizes champions), slowing them by 50/60/70% and silencing them for 2 seconds. When Nighstalker or his allies deal damage to any of the tethered enemies, all of them will take 50/75/100% of the damage dealt to the enemy being attacked (30% for area of effect damage). If Shadowshot directly hits an enemy champion, they will take 250/350/350 (+70% Bonus AD) physical damage, before the tether triggers.
Optimal Glass Cannon Build:
I hope you liked it! I feel like if this character wasn't already in Destiny, he would work really well in League of Legends. I'm not really sure why I wrote this; it's just fun for me, and I hope it's interesting enough for you. Leave a comment, saying if this would be viable or not, and if there's anything I could change. I could possibly change Shadowshot to a ground instead of a silence; but for a thematic sake, I decided to keep the silence.
