Rhonin Draig'cyfail by SnowChaser

First things first, I take no credit for any of the art used, some of it is Blizzard stuff, sum I've found on the interwebs, and some I've lifted out of bigger images. The inspiration for this character came primarily from the WoW mage ability list, a lack of arcane purpley-blue arcane looking mages, and Ezmo from Battlerite.

Throughout making this concept, I've had many an idea for talents, but not enough to make a full on talent tree (and I quite frankly can not be bothered to try and balance a whole tree of talents of anyhow) but I wanted to put my ideas outthere regardless.

Level 1-7 Talents

Passive: Regeneration orbs grant 50% bonus mana.
Quest: Gather Regeneration orbs.
Reward: After Gathering 10 orbs, Reduce the cost of Arcane Missiles by 15.
After Fathering 20 orbs, Reduce the cost of Arcane Missiles by a further 15 and gain a second charge.

Quest: Silence 15 enemies with CounterSpell
Reward: Each Arcane Missile that damages and enemy Hero reduce the cooldown of CounterSpell by 1 second.

If all 3 Aracane Missiles hit the same enemy, gain 30% movement speed for 3 seconds.

Reduce the cast time of the first 2 Arcane Missiles of a cast by 100%, Increase the cast time of the last missile by 200%, and increase it's damage by 30%. ( a full barrage still takes 100 second, but deals 10% more damage, and 60(ish) percent of the damage fast).

Arcane Missiles reduce their targets movement speed by 10%, staking up to 3 times.

Quest: Stun enemy Heroes with Nether Tempest
Reward: After stunning 5 enemy Heroes, Enemies that enter the Nether Tempest are immediately slowed by 25%.
After stunning 10 enemy Heroes, Increase the radius of Nether Tempest by 25%.

Nether Tempest does 120(+4% per level) damage when stunning an enemy Hero.

Level 13-16 Talents

Arcane Missiles deal damage in a small area around their target, dealing 50% damage.

Counterspell Slows all enemies marked by 40% for 0.5 seconds, increased by 1.5 seconds if it is activated.

Arcane Missiles deal 30% more Damage to movement-impaired enemies.

When an Enemy that Rhonin has recently damaged with Arcane Missiles dies, 1 untalented Arcane Missile Is cast from the location where it died.

Nether Tempest's Duration is increased by 1 Second, and it's cooldown is Reduced by 2 seconds whenever it stuns an enemy.

Active: Channel for up to 3 seconds, firing 3 Arcane Missiles per second. you can't move during this channel. If you complete the channel and all Missiles hit a target, reset this abilities cooldown. Cooldown: 30 seconds.

Level 20 Talents

Temperamental Flux - If an enemy Hero Afflicted with Temporal Flux, Temporal flux is automatically cast on the closest enemy Hero

Has Arrived! - Might of Dalaran pierces all enemy Heroes and Inflicts them with an untalented CounterSpell for 0.5 seconds

Master of the Arcane - Activate your trait to transform your Basic Attacks into a singular untalented Arcane Missile, Costs 30 Mana and removes Rhonin's Melee Attack

Master of the Sword - Rhonin's basic Attacks Slow enemies by 20%, deal 20% more damage, and restore 20 Mana. Removes Rhonin's Ranged Attack. Passive: Arcane Missiles do up to 50% increased damage the closer the target is.

I highly doubt these are very well balanced, some are completely incompatible with each other, and some are just bad. Still, I wanted to brainstorm here a bit, please do post your suggestions for talents, and anything else you think could be improved upon!

The vast majority of this concept was designed late at night and the numbers were theory crafted very, very loosely, so it's more than likely that Rhonin is grossly overpowered, So he'll fit right into the recent cast of HotS (I'm kidding, leave me alone) but if anyone has too much time on their hands or has theory crafted an Assassin before would like to get in touch, I am more than open to hearing what you have to say, as i am about any other constructive feedback or just generic praise <3. I would like to thank you for reading through my wall of text, and Would greatly appreciate anything anyone has to say about it, THANKS!
