"Stand back, boy, and let me show you war!" (3.5 class, PEACH)

[Jormengand]

Martial artist grants you the effects of improved unarmed strikes and flurry, along with the scaling AC and unarmed strike damage of a mnk right? So you could then pick up superior unarmed strike and get an even better punching ability?

Yes, you deal damage as though you were a monk, so if you take SUAS, you deal damage as a monk with SUAS.
