Imperius by Maximus Ultima

Level 1

[Q] Impaling Light
Celestial Charge's final damage is increased by 125% for each Valorous Brand on the target after the channel completes.
Celestial Charge's cooldown is reduced by 1.25 seconds, down to a minimum of 1 second, for each Valorous Brand on the target(s) after the channel completes.

[W] Consuming Flame
Increase the center damage of Solarion's Fire by an additional 100% and its Slow amount by 20%.
The first enemy Hero hit by Solarion's Fire refunds 30 Mana.

[Trait] Burn the Impure
Consuming a Valorous Brand deals bonus damage equal to 2.5% of the target Hero's maximum Health.

Level 4

[E] Sovereign Armor
Molten Armor grants 25 Armor for 1.5 seconds, increased by 0.5 seconds each time Molten Armor damages an enemy Hero.

[Trait] Battle Hunger
Increase Valorous Brand's healing by 80%.

[Passive] Press Forward
Increases the duration of Regeneration Globes to 8 seconds, and damaging an enemy Hero refreshes their duration.
While being healed by a Regeneration Globe, Imperius gains 10 armor.

Level 7

[Q] Flash of Anger
Consuming a Valorous Brand applied by Celestial Charge deals 120 damage around the target and grants Imperius 250 shields for 4 seconds.
All enemies hit by the AoE take an additional 60 damage over 3 seconds.

[W] Blaze of Glory
Solarion's Fire leaves a line of scorched earth along its center that applies 50% of its center damage and slow again when it explodes.
The line lasts for 3 seconds and explodes each time Imperius consumes a Valorous Brand applied to a Hero standing over it.
If Imperius is standing over the line when it explodes, it heals him for 25% of the damage dealt to enemies, increased to 50% against Heroes.

[E] Flaring Temper
Consuming a Valorous Brand applied by Molten Armor while Molten Armor is still active causes it to flare, dealing 200% damage to all enemies within its radius.
This flare heals Imperius for 25% of the damage dealt to enemies, increased to 50% against Heroes, and applies Molten Armor's Valorous Brand.

[Active] Holy Fervor
Activate to cause Imperius' next 4 Basic Attacks within 10 seconds to cleave for 30% additional damage.
Valorous Brands consumed by Holy Fervor attacks reduce its cooldown by 5 seconds.

Level 13

[Q] Pathetic Mortals
Stunning enemy Heroes with Celestial Charge reduces their Movement Speed by 25% and damage by 50% for 4 seconds.

[W] Divine Rage
Hitting an enemy Hero with Solarion's Fire reduces its cooldown by 1 second, increased to 2 seconds for center hits.
Consuming a Valorous Brand applied by Solarion's Fire reduces its cooldown by 2 seconds.

[E] Heat of Battle
Increase Molten Armor's healing against Heroes by 2% for every 1% of health Imperius is Missing.
Consuming a Valorous Brand applied by Molten Armor while Molten Armor is still active refreshes its duration by 0.5 seconds.

Level 16

[Q] Celestial Swiftness
Imperius gains 25% movement speed for 5 seconds after casting Celestial Charge.
Each enemy Hero stunned by the same Celestial Charge increases Imperius' attack speed by 40%, up to 200%, for 5 seconds.

[E] Melting Touch
Consuming a Valorous Brand applied by Molten Armor reduces the target's armor by 25 for 4 seconds.

[E] Rising Fury
Consuming a Valorous Brand applied by Molten Armor increases Imperius' attack speed by 25%, up to 100%, for 4 seconds.

[Active] Valorous Pursuit
Activate to teleport to and attack a target enemy Hero marked by Valorous Brand and gain 25 Armor for 3 seconds.
While Valorous Pursuit is off cooldown, Valorous Brands Reveal their target.

Level 20

[Trait] Brand of Solarion
Reduces the duration of Valorous Brand to 5 seconds, but Brands are no longer consumed and removed when triggered.

[Passive] Impervious
Activate to become Unstoppable and gain 75 spell armor for 3 seconds.
Basic attacks that consume at least 1 Valorous Brand while Impervious is active refresh its duration by 0.5 seconds.
Hitting Heroes with the center of Solarion's Fire reduces Impervious' cooldown by 5 seconds.

[R1] Heavenly Host
Angelic Armaments grants nearby allied Heroes 600 shields for 3 seconds.
If these shields last their full duration, they fire a sword at the nearest enemy Hero, dealing 140 damage.

[R2] Thunderous Descent
Wrath of the Angiris now deals 50% of its total damage to all enemies within a radius of 5 around the impact location.
Enemies within a radius of 2.5 of the impact location are stunned for 1 second.

[Trait] Valorous Brand - No changes.

[Basic Attack] Solarion - No changes.

[Q] Celestial Charge - Unlisted change of this ability being targeted with the cursor in the center of the ability's AoE instead of at the near edge.
This will provide better fine-control when casting this ability point-blank.

[W] Solarion's Fire - No changes.

[E] Molten Armor - The first tick of Molten Armor now prioritizes Heroes. This only applies to the first tick.

[R1] Angelic Armaments - Mana cost increased a bit.

[R2] Wrath of the Angiris - Replaced a portion of its flat damage with max-health based damage and increased its range by 1 to prevent enemies from outrunning the ability by simply walking away.
It should now be more reliable to land on a fleeing enemy. Additionally, it now deals less damage to most Assassins but more damage to Tanks, hopefully making it less undesirable to grab Tanks with this ability.

Level 1

[Q] Impaling Light - Added a 1-second-minimum cap to the CDR.
This should limit Imperius' ability to chain-stun 3+ heroes at a time by giving them a chance to scatter and escape between stuns.

[W] Consuming Blaze - Damage bonus reduced slightly and slow increased slightly to adjust for this talent's new synergy with the redesigned Blaze of Glory and Divine Rage talents.

[Trait] Burn the Impure - No changes.

Level 4

[E] Sovereign Armor - No changes.

[Trait] Battle Hunger - Healing increased slightly to bump up its performance.

[Passive] Press Forward - Now also increases the initial duration of all Regeneration Globes to 8 seconds upon picking them up, not just after hitting enemy Heroes.
This should hopefully make this talent a little more desirable.

Level 7

[Q] Flash of Anger - A portion of the damage dealt by this effect has been changed into a DoT to reduce its burst damage. It now deals 2/3s of its damage instantly and 1/3 over time to allow targets a little more time to react.
This DoT does not stack with itself, meaning this also serves as an indirect nerf to Brand of Solarion at level 20.

[W] Blaze of Glory - The line now deals half the damage and applies half the slow of Solarion's Fire's center line, and it can now be triggered multiple times by consuming Valorous Brands applied to enemies standing over the line. It also now heals a portion of the damage dealt if Imperius is standing over it, increased versus Heroes, to give it some self-sustain to compete with Flash of Anger and the new Flaring Temper talent.
This talent should now be more reliable and impactful. It also now synergizes with Consuming Blaze, giving Imperius a build for Solarion's Fire.

[E] Flaring Temper - New talent that causes Molten Armor's next tick to hit all enemies in its radius for bonus damage (but proportionally reduced healing) if a Valorous Brand applied by it is consumed while it is still active. This tick applies Molten Armor's Valorous Brand.
Paired with other talents for Molten Armor, this should give Imperius a more viable Molten Armor build.

[Active] Holy Fervor - Increased cooldown, but consuming Valorous Brands while Holy Fervor is active now grants CDR to Holy Fervor, which should allow it to have more uptime in teamfights but not in PvE situations.

Level 13

[Q] Pathetic Mortals - No changes.

[W] Divine Rage - Redesigned into a Solarion's Fire talent that grants CDR whenever Solarion's Fire hits an enemy Hero or a Valorous Brand applied by it is consumed.

[E] Heat of Battle - Now also refreshes the duration of Molten Armor by a small amount whenever a Valorous Brand applied by it is consumed.

Level 16

[Q] Celestial Swiftness - Attack speed no longer stacks across different casts of Celestial Charge, and the maximum attack speed bonus has been halved.
This will prevent chain-casting Celestial Charge against the same 3+ enemies from granting extreme amounts of bonus attack speed.

[E] Melting Touch - No changes.

[E] Rising Fury - New talent that grants attack speed every time Imperius consumes a Valorous Brand applied by Molten Armor.

[Active] Valorous Pursuit - Now also Reveals Branded enemies while it is off cooldown. However, if the target becomes Unrevealable, Valorous Brands will no longer reveal them until a new one is applied.
This should help Imperius follow Branded enemies who try to escape vision before Imperius can teleport to them without harming heroes that rely on Stealth too much.

Level 20

[Trait] Brand of Solarion - No changes.

[Passive] Impervious - Now has its duration refreshed slightly each time Imperius consumes at least 1 Valorous Brand.

[R1] Heavenly Host - No changes.

[R2] Thunderous Descent - Replaces Unrelenting Descent and causes Wrath of the Angiris to deal a portion of its damage in a large AoE and apply its stun in a small AoE upon impact.
This should now make Wrath of the Angiris a powerful teamfight tool on par with Angelic Armaments.
