[BUG] Instant death with high ES and high life regen – possible Blood Mage overflow issue ( POE 2)

Build summary:

Blood Mage archetype

Using a jewel with Alternate Tree (version 7, seed 41301, keystone selection = 4)

Life regeneration is scaled with spell casting (very high regen rate when casting rapidly)

Energy Shield pool is ~7000+, and it was still over 6000 at the moment of death

No chaos damage mitigation issues

Playing solo (no party or PvP)

Bug Description:

While playing normally, my character suddenly died instantly, even though:

Energy Shield was still very high (over 6000, not broken)

Life was regenerating quickly due to cast-based regen scaling

No visible DoT effects were active (no poison, ignite, or corrupted blood)

No clear visual indicators of incoming danger

No signs of chaos or degeneration bypassing defenses

There was no warning or visible cause. It felt like regeneration was ignored, or something directly bypassed defenses in a way that doesn't match expected behavior for Blood Mage builds.

Client.txt snippet around the time of death:

2025/10/03 16:04:14 [INFO Client 16408] : FubaHunter has been slain.

Possible cause (my theory):
As a Blood Mage, I cast skills using life. I suspect this death might be caused by a rare edge case:

My remaining HP exactly matched the life cost of the skill, and after casting, the character instantly died — even though normally, Blood Magic prevents casting if HP is too low.

If this is the case, it might be a bug in how life cost vs. remaining HP is calculated, especially in combination with high regen or latency.

Note:

No screenshot or video is available, unfortunately.

The issue is rare and inconsistent, but it has happened more than once.

Let me know if you need more information. Happy to provide more logs or test setups if required.

Thanks!
