- You're the Thief: nimble as a cat, as clever as a fox. Only you can make Sneak Attacks. You may also roll a combat die while adjacent to pick a lock by rolling anything but a Skull, search a live monster for treasure by not rolling a White Shield, or ignore a Hazard if you don't roll a Black Shield.
- Nobody is faster with the blade than you are. This card lets you roll an extra two combat dice while making an adjacent attack with your weapon. If a Hero is both adjacent to and on the opposite side of a monster you attack, you may make a Sneak Attack against it and automatically retain this card. Otherwise, if you don't roll at least 1 Black Shield during your attack, you must discard this card.

You may also roll 1 extra combat die while making an adjacent attack with your weapon against a monster you "flank" (one of your allies is both opposite of and adjacent to it). You may continue to Flank Attack monsters after discarding all of your Sneak Attack Cards.
On a seperate note, I think the Dwarf should have a new name, such as Granite Dwarf or whatever. The point is to differentiate his name from the Dwarf of the Main Game System. This avoids possible confusion in Quest notes should the Dragon Strike dwarf be played outside of your DS campaign.
Another idea for the Dwarf would be to keep his Body Points at seven, but lower his Mind Points to three like the Main Game System Dwarf. His high magic save could instead be modeled by allowing him to reroll any dice against a magic effect. This should work out the same as having 5 Mind Points (if not a bit better), but keep him more in line with other HQ Heroes.
