QUESTION: What if you cast "Sleep" on a creature and the targeted creature has more HP than the rolled Sleep HP effects? Does the Spell have partial effect or what? Thanks.

Sleep ticks up from the lowest health in the area of effect, you don't get to selectively target with it. If everyone in that area has more health than the number you rolled, the spell does nothing except waste the slot spent to cast it.

Thank you Minoke... where in the PHB/rules is that supported? It isn't in the Spell description.

It's covered in the Sleep spell itself.

A creature's hit points must be equal to or less than the remaining total for that creature to be affected.

Therefore if the target has more hit points than what is left - it simply isn't affected.

Thanks Emmber... Hmm, not sure I agree with that. Respectfully, the word "remaining" is what makes it somewhat ambiguous to only one or the first targeted creature. Let's say I target one creature and I roll a total of 99 and the first and only one creature (as you and the spell says) with 100hp or more isn't affected at all? Not even knocked prone or has disadvantage? We are told to read the spell literally and verbatim. Well, there is some ambiguity in this spell IMO, even if just a little. The one revised sentence: "All initial and targeted creatures must have equal or less than the rolled damage, or the spell has no effect." fixes the slight ambiguity. NOTE: I do understand and realize you are probably right about the spell.

The "Finger of Death" spell (I think it's called, but it may be another I'm thinking of) is another weird one. The spell kills anything 100hp or less, but has no damage to a creature with 101hp or more?! Conditional damage?!

I also don't like how the spell level and PC levels don't match. They fixed AC/THACO conversion chart issues, in making the AC make the "to hit" roll, why not spell vs PC levels? So, that's my only two complaints/issues (some spell wording ambiguity and spell levels vs PC level) with 5E... otherwise it's awesome! Maybe 6E will improve on this?!

If you rolled 99 hp for the spell and there was only one target with 100 hp - nothing would happen. The reminaing hp in that situation would be 99 and the target's hp is not equal to or less than.

If there was a partial effect then the spell would say so. The rules say what happens - if they don't say something they don't do it.

Thx Emmber.

The creature momentarily thinks it needs a nap.
