Never say 'it crashed', 'it errored', or 'it didn't work' without providing the full crash report, log, and scripts!

You can find your KubeJS startup log in /minecraft/logs/kubejs/startup.log.
If you are on 1.18 or below it will be called startup.txt.
Please send it if asked, as it contains helpful information.

its 'mob_effect.registry' up in your first line js onEvent('mob_effect.registry', event => { event.create('life_drain').modifyAttribute('minecraft:generic.max_health', '837ccc62-fc36-4485-ba50-5f218e6da42e', 0.5, 'multiply_total').color(Color.RED_DYE) })

you just have 'mob_effect'
