Emantothropes/Lycanthropes with a creature less than 1 HD?

[Coidzor]

What happens with, say, a were (http://www.d20srd.org/srd/monsters/lycanthrope.htm)-cat (http://www.d20srd.org/srd/monsters/cat.htm)halfling (http://www.d20srd.org/srd/monsters/halfling.htm) or a were (https://www.wizards.com/default.asp?x=dnd/re/20040621a)-scorpion (http://www.d20srd.org/srd/monsters/monstrousScorpion.htm) human where the base vermin was a Tiny Monstrous Scorpion? Do they have their at least 1 HD from class levels/being a humanoid plus the 1/2 HD from the animal/vermin? Does the 1/2 HD get rounded up to a full HD so that they'd have a minimum of 2 HD, 1 RHD and 1 class?

[Urpriest]

There's nothing that says that fractional HD get rounded, so I would think they just stay fractional. Makes life weird, but fractional HD were weird on the face of it anyway.

[Coidzor]

So at least go with something with 1 HD unless the benefits of a fractional HD outweighs the wonkiness of dealing with it and the hit to the HP from the fractional HD. Thank you.

You wouldn't use the 1 HD or less replaced by class levels clause?


Monsters And Class Levels
If a creature acquires a character class, it follows the rules for multiclass characters.

The creature’s Hit Dice equal the number of class levels it has plus its racial Hit Dice. A creature’s "monster class" is always a favored class, and the creature never takes XP penalties for having it. Additional Hit Dice gained from taking levels in a character class never affect a creature’s size.

Humanoids and Class Levels
Creatures with 1 or less HD replace their monster levels with their character levels. The monster loses the attack bonus, saving throw bonuses, skills, and feats granted by its 1 monster HD and gains the attack bonus, save bonuses, skills, feats, and other class abilities of a 1st-level character of the appropriate class.

Well, I'll need to re-read emantothrope, but lycanthrope's animal HD are never a character's first HD as I recall.

I'm not sure if 1.5 HD would round down to 1 HD that got replaced or not though, that's part of why I asked, though I probably should have mentioned that angle.


Skills

A lycanthrope gains skill points equal to (2 + Int modifier, minimum 1) per Hit Die of its animal form, as if it had multiclassed into the animal type. (Animal is never its first Hit Die, though, and it does not gain quadruple skill points for any animal Hit Die.) Any skill given in the animal’s description is a class skill for the lycanthrope’s animal levels. In any form, a lycanthrope also has any racial skill bonuses of the base creature and of the base animal, although conditional skill bonuses only apply in the associated form.
Skills (https://www.wizards.com/default.asp?x=dnd/re/20040621a): An entomanothrope gains skill points equal to (2 + Int modifier, minimum 1) per Hit Die of its vermin form, as if it had multiclassed into the vermin type. (Vermin is never its first Hit Die, though, and it does not gain quadruple skill points for any vermin Hit Die.) Any skill given in the vermin's description is a class skill for the entomanothrope's vermin levels.

I think "always round down" might apply here, really.

Or such lycanthropes don't exist

Or such lycanthropes don't exist

can't say for sure on entomathropes, but lycanthropy does state any carnivorous or omnivorous animal within one size category. so were-cat halflings do exist, at least in theory.

i'd say round down. that is the general rule for fractions, after all.
