Fenix (Dragoon) by vonBoomslang

Whenever Dragoon Plasma Shield is not on cooldown, 75% of the damage dealt to Fenix from all sources is dealt to his Mana instead of his health. Additionally, if he hasn't been damaged for 2s, he regenerates 1% of his maximum mana every second.
If Fenix' mana is depleted, Dragoon Plasma Shield goes on cooldown ("is disabled"), during which Fenix regenerates 2% of his maximum mana per second.

Cooldown: 5s

Fires an energy bolt at target location, which explodes after 5s or when reactivated.
The bolt deals Q (moderate) damage, but gains +10% damage for every 0.1s before detonation, up to +250%.
If allowed to charge for 1s, the explosion pushes enemies to the edge of its radius and stuns for 1s.

Cooldown: 8s from detonation.

Channel to fire a salvo of 8 energy mines (0.1s per mine) scattered over a sizable area. After 0.6s the mines arm, and will deal W (moderate to high) damage and slow (15% for 2s, stacking up to 2) enemies in a tiny AoE when walked into.
Mines that would land on an enemy instead land right next to them - close enough to damage but not close enough to trigger.

Mine lifetime: 5s.
Cooldown: 10s from start of cast.

Passive: Fenix' basic attack and basic abilities leave behind Phase Disruptor fields that deal E (light to moderate) damage every 0.5s for 3s. Damage from multiple fields does not stack except on heroes. Basic attacks create small fields, abilities create ones covering their own area of effect.
Can be activated to fire a basic attack at target area, creating a small Phase Disruptor field and hitting a single target as normal if present.

Cooldown: As basic attack.

Fenix extends his shield to protect all allied heroes and buildings in Storm Shield range. For 4s, 50% of the damage they would take is instead redirected to Fenix' mana. Fenix takes 40% reduced damage from the redirection and all other sources for the duration.

Cooldown: 60s from cast.

Calls down a drone (only shadow visible, like Hyperion) that creates a large dome shield (slightly bigger than Hyperion) to entrap enemies. Lasts 8s, until reactivated or Fenix dies, whichever comes first.
The edges of the dome block enemy skillshots. Enemies attempting to cross the edge (including leaps/dashes/blinks) take R2 (high) damage, are stunned for 0.5s, then slowed by 80%, decaying over 2s. The damage and slow duration are reduced by 50% for every time after the first.
Additionally, Fenix gains R2 (a lot) of mana for every enemy hero inside the dome when it is created. He cannot leave the dome, voluntarily or otherwise.

Range slightly shorter than radius.
Cooldown: 120s.

Enable to move 40% faster but disable abilities and attacks.

Cooldown: 5s.
