Acolyte of Chayula: Darkness Reservation vs Damage over Time

Acolyte of Chayula's Darkness mechanic does not behave according to its description when the character starts taking damage over time. Any damage over time taken by the character is always dealt to energy shield first, bypassing Darkness. At 0 energy shield, the DoT and Darkness will then behave in one of these 3 ways:

1. Upon energy shield being depleted, in *MOST* cases the Darkness pool will immediately (as in, within a single frame) drop to zero, that damage over time will start being dealt to life, and Darkness reservation will NEVER clear as long as that DoT is active. Once the DoT in question stops affecting the character, Darkness reservation clears within 5 seconds.
2. In other (rare) cases, after ES is depleted, the DoT won't be dealt to either life or Darkness, and will just prevent the ES from recharging.
3. VERY RARELY, the DoT will be dealt to Darkness (after ES is depleted) "normally", and Darkness reservation will be getting cleared individually for each tick of the DoT.

A few videos illustrating these scenarios:

- Sun Temple (lvl 66) map's persistent fire DoT debuff acting according to scenario #2 and then switching to #1 at specific debuff magnitude (breakpoint being somewhere between 39.0% and 40.0% magnitude in this example): https://youtu.be/oKV_xN1Q034
- Same debuff from the Temple of Kopec (lvl 42) zone acting the same way, with the breakpoint somewhere between 88.0% and 89.0% debuff magnitude: https://youtu.be/q_LVQ4r4IKI
- Chaos DoT ground surfaces from Fungal Artillery's FungalArtilleryFungalGroundFromMortar skill and Fungal Proliferator's FungalCascade skill (zone lvl 6) interacting with Darkness according to scenario #3: https://youtu.be/LXuwC7nViZQ
- Physical DoT ground surface from Blood Cretin's LivingBloodGroundSmall (zone lvl 14) skill acting according to scenario #1: https://youtu.be/Mj7KjuCxBvM
- Blood Priestess's VaalBloodPriestSoulrend (zone lvl 44) skill acting according to scenario #1: https://youtu.be/fIHStb9Vpic

The character used for testing is RalsBuffedFORSURE. No gear or passives changed between the videos being recorded and me submitting this, and the character has no damage taken amount/damage taken as/DoT mitigation modifiers except for poison immunity.

This issue has been present since 0.1 launch - a few threads mentioning that which I got from a literal 3-second search on the forums:

In case you are struggling with evaluating this bug's priority, do note that it makes 4 of AoC's ascendancy nodes virtually useless and therefore redundant.
