Above are some of the instances the crash happened, in short the simplest and most direct way im able to explain it is:

Get hit by wither skeleton ->
Proc reactive (ars nouveau enchant, which has been increased to level 4 with create enchantment industry) ->
Spell "harm, amplify 2, amplify 2, randomize" is proced ->
Vorpal (upped past enchant cap same way as reactive) is proced which insta kill the mob due applying properties from my held weapon which has smite and deals more damage to undead ->
Server crashes.

Yes its a lot of info but thats the most concise explanation i can give of it and i hope im not missing anything else i found note worthy.

I'll be honest here, im not even sure if this is entirely being caused by observable but none of the other mods seem really be related to whats happening so if anyone could give me a hand understanding why this is even happening id be really glad.
