Tier 1:
Raging Fires (Q): Khadgar's Q has 25% more range, and does 25% more damage, and is now a cone-shaped ability. However, it does all its damage over three seconds.
Observe and Reflect (W): Khadgar's W will shield an additional ally if he uses it on himself, though the allies shield only has 50% of the life.
Raging Beam (E): Khadgar's beam has 35% more range, but does 35% of it's damage over 3 seconds.
Tier 2:
Frostfire Bolt (Q): Arcane Barrage is instead an icicle that travels 30% quicker, and creates unpathable terrain for .75 seconds at the end of it.
If combined with Raging Fires: All along the end of the cone will have these walls.
Projected Shield (W): Khadgar's W is now a skillshot, and will grant shields to all allies it hits, but only grants 1/3 of the shield.
If combined with Observe and Reflect: Each hero hit will make it grant an additional 1/5 of the shield.
Frost Cutter (E): Fluxfire Beam will create small ice explosions instead of a beam as it travels along the path. (Approx. every half second) Each explosion will slow an enemy hero for 5% for 3 seconds, and the slow stacks.
Tier 3:
I have nothing up my sleeves... (Q): Arcane Barrage will shoot 2 additional skillshots at 45* angles, but now only do 2/3 of the damage.
If combined with Raging Fires or Frostfire Bolt: Raging fires will have a 50% bigger width, and Frostfire Bolt will create walls at the end of each projectile.
I am the party! (W): Nearby Allied heroes will also receive the mana the shield generates.
Burning Path (E): Fluxfire Beam will create a small burning wall along its path for 4 seconds, doing 35 damage per second to any enemy standing on it. Does 50% more damage against Minions.
If combined with Frost Cutter: No longer creates fire fields along it's path, but creates a freezing zone in the center of each explosion that does 40 damage per second instead.
Tier 4 (Ults):
See above
Tier 5:
I have a plan! (Q): Arcane Barrage now has a .5 second delay before it fires, but does 25% additional damage over 2 seconds.
Conduit (W): Khadgar's shield can only be applied to himself, and no longer restores mana, but nearby allies will gain 4 shield per point of damage Khadgar's shield absorbs. Khadgar's shield also has a 5 second longer CD.
If combined with Observe and Reflect or Projected Shield: The ally will still receive the shield, however, Conduit shield given by allies is halved. Projected Shield will also gives allies the shield, but Conduit shield given by allies is only 1/5 of the value.
Break Their Lines (E): The beginning of Fluxfire beam can only be cast on an enemy and will start at the enemy, but you may still vector target from said enemy. Range of Fluxfire Beam is increased by 25%, and it does 10% more damage.
Tier 6:
Bouncing Force (Q): Arcane Barrage will ricochet at a 90* angle from an enemy, or will bounce 45* from a wall. Arcane Barrage has a 25% longer range.
If combined with I have nothing up my sleeves, Raging Fire, Frostfire Bolt: Each individual projectile will bounce, the Fire cone will travel along the wall for a total of 50% of it's range, and when hitting an enemy or a wall, Frostfire bolt will create a wall too.
Burning Shield (W): Focused Shield can only be cast on enemies, and gives enemies 10 armor, but will take an additional 20% of all damage taken over 3 seconds. Focused shield won't give an enemy a shield.
If combined with Observe and Reflect, Projected Shield, I am the party!, Conduit: Burning Shield only will take an additional 10% of all damage over 4 seconds on the second vitim, Projected Shield will apply to all enemies, but they will only take an additional 5% over 3 seconds, I am the party will spread half of the damage over time taken to nearby enemies, and Conduit will do a third of the damage over time to nearby enemies.
Blazing Beam (E): When Fluxfire Beam goes on it's second route, it will instead explode in a cone of fire, doing it's damage instantly to any enemy affected.
If combined with Frost Cutter, Burning Path, Break their Lines: Enemy heroes hit will be slowed by 25% for 2 seconds, a fire field will be created on the path of the explosion, and the first part of the beam won't happen so the explosion will be instant.
Tier 7:
Rapidfire (R1): Firespitter will now explode every second, doing 100% of it's DoT damage instantly in addition to applying the DoT.
Freeze! (R2): Splitting Wall now traps enemies in a circle, but each wall does 25% of it's damage.
... But using it wisely, is the key. (R3): Doubles basic attack damage, mana gains are doubled, and Khadgar will automatically basic attack a second enemy.
The Might of Dalaran: Khadgar will summon Dalaran over the battlefield. Dalaran will remain for 5 seconds, and summon 1 Dalaran Mage every second. A Dalaran Mage has twice the damage, attack speed, and life of a ranged minion, and each attack made restores 3 mana to Khadgar. Dalaran will also fire a large arcane missile every 2.5 seconds at the highest life hero, doing 300 damage per missile.

On the actual design itself, a few notes.
First, with him having a shield ability, im not sold on Assassin. I mean i get it, it returns mana, and he uses a lot of it, but is there not another way to restore mana while still dealing damage or being offensive, without stepping on medivh's toes? Otherwise it pegs me as a specailist like he is. Maybe make it so its only usuable on himself but gains a more powerful benefit?
His Trait is super great. I love it. An auto attack based mage! Thats new and exciting with some great synergy with certain heroes like say varian with Dalaran Banner. My only critique is you dont build off it enough. It seems just there, just to be there. I would like more synergy with the rest of his kit, maybe even making that the core of his kit, because thats a slam dunk of an idea for a kit right there. An Auto Attack Mage.
The Q while straight foward is rather bland. Like If I read to you probius's Q without telling you what it does to his W(Warp Rift) you would think its really boring, but his interaction with Warp Rift makes it fun. Maybe do something similar? Making it gain additional benefits like the "cleave" arcane barrage in wow has when interacting with an ability(s) or possiblity additional damage.
The W, again, seems out of place. As a high damage assassin in his description. Him having support capabilities doesnt seem right to me. Maybe if it increased his damage for a short period aswell or something.
The E, the implication seems unnecessary. What would vector targeting change that a simple cone spell wouldnt, other than the initial direction the beam comes from. It seems vector targeting doesnt really enhance the way this spell plays, unlike Living Meteor on Ragnaros or Force Wall on Tassadar. And again, it doesnt really seem like its fitting with his kit. It seems, just "there". The trait off the bat implies one thing but then his kit is very cooldown ability based with a ally sustain ability? Seems too all over.
Z also seems unneeded. I dont like copying spells. I didnt like it when Morales got the same trait as Muradin and Im glad no other hero really did that. Let the raven be Medivh's identiy. Im aware Khadgar could also do that in WoW, but lets not do that in hots. lets make khadgar awesome for being khadgar, not being a medivh clone.
R1- The design itself, FANTASTIC. Great. I imagine it plays kinda like Dva with her Defensive matrix in terms of movement, which is kinda what it does in the clip. I would clean up the wording though to make it consistent. Like it doesnt need to only apply 2 stacks of burning on the initial cast rather than subsequent ticks. That seems like a lot of word fluff unnecessarily.
R2- Cooldown is way to long. I would suggest lowering to about 30-50 seconds. I imagine its a buffed up Tassadar Wall that does damage but also can be killed to break though. The only thing is you dont want to punish enemies for killing it, since thats the counterplay. You want it to be more rewarding when you set up a icewall so good they dont have time to kill it, making it even more deadly.
R3- Seems really uneeded and actually counter intutitive to the idea of the trait. Which leads me to the next part of..
You really need to think of the overall arcing identity you want for Khadgar. Jaina is an utility AoE burst mage with slows. Kealthas is an utility AoE burst Mage with a stun. Li Ming is a Mobile burst mage with Tempo swings. Guldan is a Sustain damage Mage with self healing. Nazeebo is a Sustain damage mage with summons.
Chromie is a Long Range Burst Mage. With each one I know exactly what their goal is, when to draft, what they are strong with and weak against.
Who is Khadgar? what should I think of when I think of this hero. What should I draft him for? His trait implies one thing but then the rest of the abilities is your standard cooldown based Burst mage.
If you want to make him that way, Give him a way to spend his Mana faster for bigger results. For example, make it so I can use up literally my entire Mana bar in less than 5 seconds for HUGE damage but I have to sustain myself by auto attacking or shielding (himself only) to restore mana and keep going. Give him a clear goal.
Personally I see it has 2 directions you can choose to go from. An auto attack based Mage , or a Mage who uses tons of mana then tries to restore via auto attacking or self (only) shielding.
Again, love the presentation. I wish more concepts had your visuals. I know this is a WIP and I would love to see it more fleshed out.
