This is the doppelganger monster class, presented in Savage Species format, except using the current ("3.0" August 2000 release) Monster Manual rules. The doppelganger was never scheduled to appear in Savage Species; I wrote this version in December 2002.

You probably still need to have Savage Species to use this table, just so the format and such makes sense, but if you can figure it out without the book, more power to you.

Note several main differences between what is presented here and what is in Savage Species:

• The monster is given skill points over the course of the class so that it ends up with the number of skill points presented in the MM; these skill points are based on the default Int of the monster in the MM, and unique characters taking this class do not get more or fewer skill points based on Int.
• Ditto for feats.
• Monsters taking these classes gain skill points and feats only when these tables say so; they do not gain skill points every level or feats every 3 levels like normal characters do (or like how Savage Species says they will in the "D&D 3.5" Monster Manual). Places in the table where the creature gains no skill points are intentional.
• The table is going to look front-heavy with skill points and feats. That's because some kinds of creatures (particularly fey, shapechangers, undead) have skills and feats at their 1st hit die based on Int, and I didn't want to shortchange the PC built with a monster class; the monster classes were built keeping in mind a typical low-hit dice creature of that type in mind (in other words, progressing through the doppelganger class wouldn't shortchange you in skills & feats compared to other shapechangers of the same HD). If it bothers you enough, spread those early skill points and feats over more levels.
• It has been pointed out to me that the previous point means that (due to max skill rank limitations) some creatures progressing in a monster class can't exactly duplicate the final result in the MM. Yeah, something needs to be done about that, since a monster with 20 skill points at 1st level and only 3 class skills is going to be forced to spend skill points on non-class skills, which is not good. I'll come up with a solution later (probably by a more even distribution of skill points, which may mean reworking the table, as some levels are balanced by gaining several abilities but no skill points).

• Size Medium.
• Speed 30 ft.
• Int +2, Cha +2
• Darkvision
• +2 racial bonus to Bluff & Disguise checks (this racial bonus increases to +4 at level 4). When using alter self, a doppelganger receives an additional +10 circumstance bonus to Disguise checks. If it can read an opponent's mind, it gets a further +4 circumstance bonus to Bluff and Disguise checks.
• Automatic language: Common.
• Proficient in simple weapons and no armor.
• Class Skills: Bluff, Craft, Disguise, Listen, Profession, Sense Motive, Spot.
• After level 8 doppelgangers gain feats normally according to their total ECL.
