Sneak attack damage from weapons

[Nymaen]

When you get extra sneak damage damage from a weapon feat or stance (like knife or fencing), do you need to qualify for a sneak attack to use that extra damage (i.e. flanking the target). Or do you just get an extra die of damage that can get negated by anything that can normally not be affected by a sneak attack.

Welcome new comer!

They're called sneak attack dice for a reason: they only apply when making a sneak attack (see page 211 in the 2nd printing)

It's the former. As I always say, Sneak Attack Damage is a conditional type - in order for it to apply, the character has to be vulnerable/flanked, has to have vitals to strike, etc. etc.

Can any character gain 1 die of Sneak Attack as long as they meet the Condition requirement on page 211?  It says "When a character possesses 1 or more dice of sneak attack damage, he may use them to augment the damage of any Standard Attack..." 

But other than Misdirection Supremacy, I have not found any Feat or Class Ability which grants the ability Sneak Attack.  The Feats and Class Abilities which mention Sneak Attack dice say additional dice are granted.  How do you get the initial one die?

Thanks

Any ability granting a die that doen't require you already have one serves as giving you that initial die.

Any ability granting a die that doen't require you already have one serves as giving you that initial die.

For example, any character can gain sneak attack dice using a Tactics/Ambush check, while some classes (most notably the Scout) grant Sneak Attack dice outright.
