Hello once again. This is my newest concept: Aeria, the Mist Archer. Leave a comment if you'd like to :D Thanks in advance, though I'm not sure if I could reply right away, but I will.
Innate: After casting an ability, Aeria's next basic attack becomes a pass-through skill shot, dealing Error: Parameter '3' is not accepted.% of AD to all enemies in a line and applying on-hit effects to the 1st enemy hit. This ability lasts for 5 seconds.
Everytime the arrow hits an enemy champion, its current damage is reduced by 10%.
Activeive: Upon activation, Guided Shot will persist for 5 seconds or after Aeria triggers the effect by her 1st Mist Arrow within the duration. After 1 second of her 1st Mist Arrow, a mimicked version of it will be launched from Aeria's current location, which will travel parallel to it and deals magic damage to all enemies it passes through.
Active: Aeria becomes one with the mists and dashes a fixed distance towards the location of the cursor, ignoring damage in the process. Within 5 seconds of activation, Aeria's Mist Arrow will deal bonus physical damage.
Active: Aeria calls upon the mists to aid her in battle, resetting the cooldown of the last ability she used to 0.5 seconds and gaining bonus attack speed for 3 seconds.
Guided Shot acts as a buff that lasts for 5 seconds. Within this time, Aeria should perform a basic attack which is the Mist Arrow. After 1 second of that basic attack, the buff will shoot an arrow parallel to the basic attack she performed.
I made Mist Rush and Mist Step share cooldown, since both of them acts as an escape tool. Also, if a mobility type ability can be used while disable or if a champ has an escape ability and at the same time with a mobility ability, that would be OP.
