Martial and Psionic Blended?

[Khyell Hyre]

There is any PrC wich blends both niches?

[Eldest]

Battlemind? Just the entire class?

[Seerow]

Psionic Warrior is good from level 1 to 20, or War Mind is a great prestige class granting full BAB and a good chunk of psionic warrior manifesting progression crammed into 10 levels.

If you mean Martial Adepts, I don't think there's anything by default, but homebrewing something like a modified Jade Phoenix Mage isn't difficult.

Or there are several homebrews. I'll now shamelessly plug my own base (http://www.giantitp.com/forums/showthread.php?t=183826#post10181086)* and prestige (http://www.giantitp.com/forums/showthread.php?p=10911776&postcount=64) class which combine psionics and martial maneuvers.

Eldariel made the Ephemeral Blade (http://www.giantitp.com/forums/showthread.php?t=107034&highlight=ephemeral+blade), combining Diamond Mind, Iron Heat and White Raven with Psychoportation. I made the Jadewind Blademaster (http://www.giantitp.com/forums/showpost.php?p=10887776&postcount=3), which combines the Diamond Mind, Tiger Claw, and Psychokinesis disciplines.
