Draconic Evolution can kill players wearing MI quantum armor

[James103]

To setup the testing environment, install the following mods and their dependencies, or install the modpack "All the Mods 10" version 6.1:

• Draconic Evolution 3.1.4.632
• Brandon's Core 3.2.1.309
• CodeChicken Lib 4.6.1.526
• Modern Industrialization 2.4.1
• GuideME 21.1.15
• NeoForge 21.1.219
• Minecraft 1.21.1

To reproduce this:

1. Create a new world with the above mods installed or in All the Mods 10.
2. Go into survival mode.
3. Give yourself and equip a full set of MI quantum armor.
4. Go to the End dimension and make your way to coordinates /execute in the_end run tp @s 10000 100 0 or any integer multiple thereof. You should see a Chaos Guardian and its island along the way.
5. Wait until a Chaos Guardian engages its signature laser beam on you.
6. After approximately 6 to 8 seconds of firing, you will die.

A death achieved this way is caused by the following code path being triggered, which, as far as I understand, completely bypasses the hurt method which the quantum armor injects at the beginning of to cancel its execution. At no point did a Totem of Undying I had equipped in my offhand get popped, even during the ticks before and after that kind of death.

Assuming a full set of MI quantum armor is intended to protect players from all sources of damage, even from the /kill command, this is an exception.

Here are my results from three different tests of whether the player can die from the Chaos Guardian while wearing full MI quantum armor:

Test 1: Survival mode, full quantum armor, no totems — Result: Quick death
Test 2: Survival mode, full quantum armor, totem in offhand — Result: Death after a few minutes, no totems popped.
Test 3: Creative mode, full quantum armor, totem in offhand — Result: Survival after one hour, no totems popped. Observation shows the guardian flying within the arena with no interest in fighting the test subject player.

Full quantum armor was simulated with the command attribute @s modern_industrialization:quantum_armor base set 4. Any value > 4 in that command has the same results as if it was 4.
Totem stacks used in tests 2 and 3 were generated and equipped in the offhand by the command item replace entity @s weapon.offhand with totem_of_undying[max_stack_size=99] 99.

Continuing tests since previous update...

Test 4: Survival mode, full quantum armor (real items in armor slots, not simulated with attributes), totem in offhand — Result: Death after a few minutes
Test 5: Survival mode, full quantum nano armor (real items from EI in armor slots, not simulated with attributes), totem in offhand — Result: Death after a few minutes. One chaos guardian took too long to fire its laser beam so the test subject was teleported to another guardian.

All five tests were done using freshly spawned/generated Chaos Guardians and their arenas.

The comment in the linked source code is very clear about the dev's intent, and Draconic Evolution has had this "directly force death" behavior for over 3 years. In fact even in 2015 the attacks were able to kill Creative Mode players.

This is a case of "unstoppable force versus immovable object". One mod's preference has to trump the other. Even if MI made some sort of change to prevent this death, DE would surely just make even more changes to get around them. Especially true since the most popular 1.20 and 1.21 modpack uses both of these mods together.

Thanks for the investigation. I don't really want to start an arms race with other mods (especially DE :))
