[Suggestion] AoC Darkness Rework

I believe most people agree that the current implementation of Darkness is pretty lackluster. I just wanted to share an idea I had for how it could potentially be redesigned!

Embrace the Darkness
Removes all Spirit.
Your Dodge roll generates one Layer of Darkness.
Sprinting quickly generates Layers of Darkness.
Mantra of Destruction generates 5 Layers of Darkness.
Maximum 5 Layers.
Each Layer grants you x Darkness (x = Spirit value).
Lose one Layer of Darkness when hit.
Darkness absorbs damage equal to current total value when hit.

Concept
Numbers may need balancing obv, but the idea is a defensive option that scales well with evasion (since Invoker gets ES boosts).

Rather than just being an extra health bar it functions as a very strong mitigation that gets weaker each time you're hit before wearing off. This feels close to what the intended design for the skill is in the first place and pairs well with evasion where you expect to only get hit once or twice as you engage into melee.

In theory this would give the option to go full evasion and not feel like it's such a gamble diving into many enemies.

Added interactions with dodge/sprint and Mantra of Destruction since this feels thematic and gives interesting synergy with other skills in AoC kit and ascendancy.


Bonus Idea!!
Since losing your Spirit removes a lot of options I think you should get a Meta skill when investing into Darkness so you can still come up with interesting builds.

Dark Invocation
Gains x energy when you generate a Layer of Darkness.
Maximum energy 500.
Socketed spells consume 10 energy per 0.1 seconds of base cast time when triggered.
Lose 1 Layer of Darkness on activation.

Concept
Early game energy is balanced to require you to generate multiple layers for a cast. Late game you become less and less likely to lose layers, but 1 Layer is always guaranteed lost on cast so with enough +energy stats you can self sustain to a degree.


Conclusion
Just some fun I had when I couldn't sleep last night. Would love to hear some thoughts :3
