Fenghuang, Chinese Phoenix

Fenghuang: The Phoenix( Mage)

Passive:Spread Your Wings:While out of combat, Fenghuang flies and is less susceptible to vision. He gives off half the vision range while out of combat for enemies to see, but he can still see normal distance. Wards will only see Fenghuang at 3/4 of their range.

Ability 1: Scatter Flame: Fenghuang scatters tiny balls of flame in an area around him( size of odin's 3). He will randomly turn into 1 of these flames and gain 10%/15%/20%/25%/30% more movement speed for 3.2/3.4/3.6/3.8/4 seconds( his hitbox is still the same, but he just appears smaller and the flame is located close to the ground). The flame he turns into is random every time the ability is used. Fenghuang's flame will deal 60/70/80/90/100(+10% magical damage) to all enemies passed through. Enemies can only be damaged once.
Mana: 50/65/80/95/110
Cooldown: 15 seconds

Ability 2: Intensify: Fenghuang intensifies his flames and deals 5/20/35/50/65(+10% magical damage) ever second in an area around him while active( size of odin's 3) This ability can be activated and deactivated when clicked.
Mana: 20/25/30/35/40 per second
Cooldown: 2 seconds

Ability 3: Flaming Caltrops: Fenghuang Huang places a bunch of flaming caltrops in a 15 unit area around him( between the size of Ymirs ultimate and odin's 3). There will be 8/9/10/11/12 evenly distributed caltrops in the area. Once one is stepped on it disappears. Each caltrop deals 40/50/60/70/80(+10% magical damage) to all enemies in the area. These caltrops will slow for 10%+1% for every other one stepped on.
Mana: 60/70/80/90/100

Ability 4: Fire Bird: Fenghuang flies forward in a line the length of agni's dash and width of ao kuang's ultimate( his wingspan) as fast as ao kuang's ultimate's movement speed, and activates .3 seconds after it is pressed to go. It will deal 260/320/380/440/500(+60% magical damage) to each enemy hit, and pushes all enemies back about 5 units( similar to Hercules dash) and stuns them for 1/1.1/1.2/1.3/1.4/1.5 seconds.
