It might be prudent to change the name since the Vampiric Mist already has official stats in 5E.
How about Scarlet Mist, since our Crimson Death analog is renamed the Scarlet Death Mist?
Or we could use the original name of the monster, the Vampire Mist or go back to your earlier proposal of Blood Mist.
I'm also considering statting up a monstrosity version modelled on the original AD&D Vampiric Mist, since that had some noteworthy differences from the Dungeon Magazine #221 version.
Okay, let's get started on the "
Scarlet Vampire Mist" or whatever we end up calling it.
Since we're basing it on the 4E
Dungeon #221 version, the
Size & Type is going to be a Medium undead.
The 4E version has
Alignment: evil, so I'd make it
Neutral Evil rather than
Chaotic Evil, since (a) 4E has a CE alignment (it being "More EVIL than Evil") which it didn't assign to the monster, which leaves us with LE and NE. It doesn't seem very lawful and the original AD&D Vampire Mist was a NE monster.
The Dungeon version also had the "shadow" origin to indicate it came from the Shadowfell. That plane still exists in the current edition but the 5E monster statblocks don't use an origin entry, so we'll have to remember to mention that in the
Description.
Next is
Armour Class. The Fourth Edition version has "AC 23, Fortitude 21, Reflex 21, Will 19," which is a pretty average AC and saves for its Level of 9 since 4E suffered from extreme stat inflation. The Will is a bit low, but we can reflect that with a poor Wisdom score.
I'm thinking Armour Class 13 and ability modifiers of Dexterity +3, Constitution +3 and either Wisdom +0 and Proficiency in Wisdom saves; Wisdom +2 and no Save Proficiencies at all or just Wisdom +1.
It's a weak monster, so doesn't really need Saving Throw Proficiencies.
Regarding
Abilities, the 4E version has:
Str 7 (+2) | Dex 21 (+9) | Wis 17 (+7) |
Con 20 (+9) | Int 5 (+1) | Cha 9 (+3) |
While the official 5E
Vampire Mist has STR 6 (–2), DEX 16 (+3), CON 16 (+3), INT 6 (–2), WIS 12 (+1), CHA 7 (–2).
If we follow the odd-even arrangement of the 4E version and step the numbers down a bit to match the typical ability scores of 5E, that'd be something like STR 7 (–2), DEX 17 (+3), CON 16 (+3), INT 5 (–3), WIS 13 (+1) or 15 (+2), CHA 7 (–2).
Of the Wisdoms, I'm leaning towards the higher WIS 15 just because that matches the standard 5E
Vampire.
I'm tempted to either slap on another Hit Dice or cut one off, mostly to distinguish it more from the official Vampiric Mist.
