I did a check again with power word kill against a CR 5 myconid spore again - It only gave a notice that it was blocked due to death spell immunity, so I guess last time I tested I got mind spell immunity notice because I held it with a bigby to check the range.Nemni wrote: ↑Fri Feb 14, 2020 4:50 pm Haven't tested it, but I can't see anything in the script for power word kill about it being blocked by mind immunity. There's no delay when targeting a single creature either, it's as instantaneous as any other instantaneous spell (which means instant effect, not instant casting time).
About the instantaneous - The thought was to make at an instant cast time - like uttering a single word.
I agree with that, I think the challenge is to make it unique and not just another save/or else spell, but on the other hand the way it is now is utterly useless.
