Include sneak attack w/ Critical?

[Dheran]

Would Uncanny Dodge negate Telling Blow then?

Telling Blow's function to add sneak attack damage is predicated on making a critical hit. Uncanny Dodge lets you retain your DEX bonus to AC when caught flat-footed or struck by an invisible attacker. Confirming a critical hit is all that's required for Telling Blow, so Uncanny Dodge does nothing to stop the sneak attack damage allowed by this feat.

Good or bad? Telling blow would be a little too nice if the dice were multiplied.. sure, a pick would result in humongous damage, but I think in practice, it would be overkill in mony cases... in practice rapier would be more consistently good. Certainly too good for a feat, IMO..

If it's an issue I think the best solution may be to vary the die size depending on the multiplier:
x2 - d4
x3 - d6
x4 - d8

Still weighted towards the higher threat ranges but a little less so...
