Extreme Dexterity (& Intelligence)

[ImperatorK]

I'm making a character that's going to be extremely Dextrous and Intelligent. He's going to be gestalted, witch a powerful race and templates on one side of the gestalt and class levels on the other. I need suggestions for said race and templates. It was easy to make an extremely Strong and Tough character, but it's harder to find stuff with good Dex and Int.
Here are the requirements, limitations and houserules:
- 20 CR
- can't be smaller than Small or bigger than Large
- you can ignore template requirements for size, type, alignment or the like
- race and templates can be anything as long as it's humanoid in appearance or can be refluffed relatively easly as such
- high Dex and Int are a priority, but other stuff is welcome
- no same template stacking, unless it's specifically allowed by its rules

Probably missed something.

Marruspawn from Sandstorm might work. Marrulurks are widely considered one of the few races worth the HD and LA. Add the shadow creature template and class levels to taste, probably factotum, rogue, or assassin. Just make sure to place a high number of points in its Int score.

Also, marruspawn abomination is pretty good on those scores.

Would refer to bhu's thread for template candidates

Outsiders are probably the best place to look, alternate form should cover appearance requirements.
Those with regeneration can help make you a bitch to kill as well...

Phrenic is a lot of bang for the buck in Gestalt

(Steel & Mercury) Dragon using aging as a 'buff' (Curse & River's) vould be pretty tough, but probably not dexterous. Int via Riddled.

Do you mean ECL 20?

[ImperatorK]

No, CR 20. Race CR + Template CR + class levels.
