Zero (Mid range DPS frost mage)
Passive: Frozen Over Damaging abilities apply stacks of Frost, each of which apply a 10% movement slow, with each instance of damage, lasting 2 seconds. If the slow is stacked 10 times, the target will be stunned for 1 second and dealt 20 (+5 per level) (+.25 AP) magic damage. After the stun wears off, the slow will be limited to 2/4/6 stacks on that target for 8 seconds.
Q: Rite of Freezing 12/11.5/11/10.5/10 second CD, 90/100/110/120/130 mana (drained over the duration of the spell) For up to four seconds, channel a beam of freezing wind towards your cursor, extending 550 units. This beam deals 10/13.3/16.6/20/23.3 (+.066 AP) magic damage per tick, three times per second. (30/40/50/60/90 (+20% AP) magic damage per second) While channeling the beam, you move at 20% speed and cannot basic attack. Reactivate to cancel.
W: Cold Snap 15 second CD, 110 mana All enemies in a 300 radius of the target enemy (700 range) take 8/10/12/14/16 (+.075 AP) magic damage for each stack of Frost caught within that area. All enemies damaged by this ability have frost stacks applied to them equal to the highest stacked unit in the area (plus one from the damage).
Minions and small monsters caught in the area cause 25% of the normal damage.
E: Chilling Aura 2 second CD, 20/25/30/35/40 mana per second Toggle: Enemies within 650 units are chilled. Chilled units move and attack 8/10/12/14/16% more slowly, and their cooldowns tick down 10% more slowly.
For each chilled enemy champion, Zero regenerates 10/12.5/15/17.5/20 mana per second.
R: Rune of True Ice 110/100/90 second CD, 100 mana For the next eight seconds, your other abilities are empowered.
Frozen Over Stun increased by 0.25/0.5/0.75 seconds. Damage increased by 10/20/30%.
Rite of Freezing Reduce base CD by 2/3/4 seconds. Extend range by 100/200/300 units. Change from a line to a 30 degree cone.
Cold Snap Reduce base CD by 2/4/6 seconds. Increase radius by 50/100/150. Extend range by 200/250/300/.
Chilling Aura Now deals damage every 1/0.75/0.5 seconds, equal to the damage dealt by one tick of "Rite of Freezing" CD increase amped by 5/7.5/10%.
who I'd consider a DPS mage (albeit she's more like a machine gun). She has a fairly shorter range with her E, and it relies on her landing her poison in order to show it's true shine. Once it does though, it allows her to continuously pour our dmg... and she has defensive capabilities with her ult and her e's heal (which does exist besides it's low stats). I just can't seem to find how your character would be able to survive a battle really, as his only defense seems to be his CC (his CC poses some issues as well, but I'm not an expert regarding that, so I'll try to think on it and come up with a good way of stating it later).
