Behold. The most OP spell in all of DnD.

 be older than 15. Play dnd3. We sling save or die spells there at lvl 7.

Imagine being so narrow-minded, that u call the latest thing "all of".

I agree with Antares8001....       ....or if it was a 6th or 7th level spell instead...

 at 20th level, wizards have 2 6th and 2 7th spell slots, so you could cast it 2 times if it was for either a 6th spell or 7th spell , while saving your 9th level spells for something of a more pizzaz. I think I see a problem

Does this spell override that thing some legendary creatures have? The ability that when they go to 0 health, they go back up to a certain amount and have mythic actions afterward. Since this spell automatically kills the target (if it under 100 health), does it skip past 0 health and the ability doesn't activate?

sounds strong

Kill as in 0 HP and save, or kill as in "roll a new PC?"

this killed my friend it made me sad :(

 Probably the latter.

I like to imagine the power word sounds something like "Hey guys, did you know that Vaporeon"

As a DM, you have to meta game to use this spell

As a player, its hit or miss

Quote from Hector12909 >>

Cannot, only if the max HP is 100

 

 Incorrect

Avada kedavra

0 HP and save is knocking them unconscious, so i think (but might be wrong) it's just roll new PC

Kill as in roll a new PC.

Quote from Tamakins >>

Does this mean you can use it on a creature whose hit points have dropped to 100 or below?  Or can you only use it on creatures with a max HP of 100 or below?

 Both

works like 3 failed saves I imagine, revivify, raise dead, resurrect, and true Resurrection still work here. 

It should be a DC 20 con save

I swear use Quicken spell w/ SP As a sorcerer >:D

Quote from MyzticManor21 >>

 A Chain Warlock casting it through his familiar can kill someone with an invisible sprite while he's in the next room over.

That's not something a chain warlock can do, though.

 voice of the chain master: allow me to introduce myself

I know this line of comments is quite old, but just in case anyone sees it and is misled: the Voice of the Chain Master Eldritch Invocation allowing the Warlock to speak through their Familiar does not interact with spellcasting in any way. Totally understandable for one to misunderstand this with a thematic reading of the feature, but since it lacks language referring to "spells with only a Verbal component" or somesuch, it does nothing to extend the limitations of spell delivery from the Find Familiar spell.

To be clear, this spell does NOT drop the target to 0 Hit Points. It instantly kills the target. The only things that can save you are having more than 100 Hit Points (temporary Hit Points are not counted), being immune to spells, or having a Death Ward on you.

roll a new PC
