Bardsandsages said:A few things:
A vampire gets a +6 bonus to Strength. This means an extra +3 to attack and +3 to damage rolls. Assume for the sake of arguement the base 5th level creature is a fighter and already had a strength 16. You now have a creature with a Strength 22. Put a Greatsword in his hand and without any feats he's doing 2d6+9 damage on a successful hit, and has a +11 to his attack roll.
And only one attack per round. And 8 less BAB, which makes his attack bonus a net 5 lower. Sure, 2d6+9 per hit without equipment is nice, but it means nothing if the vampire can't hit anything. Also, the standard-race fighter we're comparing him to could simply Power Attack for 5 points, making his attack bonus equal to the vampire's, but doing 2d6+14 damage, with two other swings after the first for the potential for even more damage. Advantage: Standard-race fighter.
Bardsandsages said:Add to this that this fighter has a Natural Armor bonus of +6 and a Dex bonus of +4. Assume his base Dex was only 14. As a vampire it becomes an 18. Before you even put any armor on him his AC is 20! Oh, wait, he gets the Dodge feat for free. So his AC against a single opponenet would be 21.
The +6 Natural Armor is a nice bonus, and I'd forgotten about that one. But as for the Dex, lots of fighters go for full plate, which means Dex isn't really an issue. All you need is a 12 Dex, which is easy to get.
Bardsandsages said:A vampire properly designed and equipped is a deadly PC as a fighter. Maybe he doesn't have as many hit points as a 13th level fighter, but he's automatically healing 5 a round anyway.
No, he's not deadly. He's useless because he only gets one attack compared to three for a standard-race fighter, and he can't even hit anything with his one attack. And as for soaking hits, sure he's harder to hit than the standard-race fighter, but once he does get hit, he's going down in a hurry. A 13th level fighter with a 20 Con (perfectly feasible at that level) will have 141 hit points to the vampire's 38.
And healing 5 hit points per round is pretty much insignificant at 13th level. And don't forget that the vampire can't be healed in combat unless the party has a neutral or evil cleric willing to memorize Inflict spells (and thus be worse at healing the rest of the party).
Not to mention that, against intelligent foes, the vampire's hit points won't even be an issue, since they'll ignore the guy who's waving the sword in their faces ineffectually and go after the rest of the party members, the ones who are actually a threat.
