Harrid Monster Class

As soon as I saw the Nekharu faction from Crocodile Games, I knew I'd want to use them as "apprentice" versions of the harrid monster from Monte Cook's Diamond Throne setting for Arcana Unearthed (in fact, I picked up a Nekharu coven witch with dagger and a Nekharu coven witch with dagger and skull at Gen Con Indy 2004 just for this purpose). I thought about writing this up in a weakened form as an "apprentice harrid," then I realized it would be better to present them it a monster class a la Savage Species, with one class level for each of the harrid's HD or LA ... that way I could make any form of "teenage harrid" I wanted to suit any low-level adventure. This is the result, using the 3.5 ruleset (monsters get skill points per hit die like character classes do, feats every 3 levels, etc.).
The name "harrid" is used with permission from Monte Cook.

Here's a quick summary of the monster class rules.

Not all levels in the monster class give you HD, BAB, saving throw advancement, and fun things like that. That's intentional, as the number of monster class levels equals the monster's HD plus its LA, and therefore any creature with an LA is going to have that many levels that don't give HD-based goodies. Instead, we use those levels to add in the monster abilities that are the cause of that LA.
With monster classes, you only get skill points when the class table indicates you do (as some levels in the monster "class" don't give you hit dice and you only get skill points when you gain HD). Thus, places in the table where the creature gains no skill points are intentional. A harrid character gets x4 skill points at 1st level, just like a normal character class.
As with the skill points, so it is with feats. The class only gives you feats when the table says so, not automatically at level 3 and 6.
The class grants ability score bonuses at certain levels; these are typeless bonuses (the class spreads the creature's racial ability score modifiers over several class levels instead of all at once) rather than enhancement or any other type of bonus. Note that the standard harrid has a racial +6 to Intelligence, but the monster class starts them out at +0, which means that a character built with all seven levels of the monster class isn't getting as many skill points as the default harrid; to fix this problem, when the harrid gets an Int increase from the monster class levels, retroactively apply the Intelligence increase to its previous levels (and remember the x4 at 1st level). It can immediately any the bonus languages from its increased Intelligence (most harrids learn Common and Giant).
You can't multiclass into the harrid monster class; you're either a harrid from the start or you're not a harrid at all.
According to the rules in Savage Species, you can't multiclass until you've finished all of your monster class levels. Some people think that rule shouldn't be there; I do.
This monster class doesn't include the default 1st-level in a spellcasting class that all "adult" harrids have; add that in separately. That's also why the CR listing stops at 4 (the CR 5 in the harrid monster writeup includes the default harrid's 1 class level).

    Spell Resistance (Su): At 2nd level, a harrid gains spell resistance 5. This increases to SR 10 at 4th level and SR 15 at 6th level.
    Bite: At 2nd level, a harrid gains a bite attack for 1d6 damage. This is a secondary attack to its claw attacks.
    Spell-Like Abilities: At 3rd, 5th, and 7th level, the harrid gains the ability to use the listed spell-like abilities.
    Magic Drain (Su): At 4th-level, the harrid develops the ability to use its magic drain ability, though in a weaker form than that of a mature specimen of its race. Instead of automatically working, the target creature or object gets a saving throw (Fortitude DC 10 + 1/2 harrid's HD + Charisma modifier) to resist the effect. At 7th level this ability fully matures and no longer gives the target a chance to resist.
    Poisoned Weapons (Ex): Once its magic drain ability develops, other harrids see the young one as nearing full maturity and teach it how to make the deadly poison all adult members of this race use. Thereafter the young harrid makes and uses the poison as a sign of superiority over its younger counterparts.
