From the Designer's Website:
Vous etes des legendes.
User Translation from French:
You are legendary.
("Dernier Sang" is French for "Last Blood".)
Characters have 10 points to distribute between three attributes: physique (physical), mental (mental), vie (life).
Task resolution is performed by rolling a number of six-sided dice equal to the appropriate attribute value, keeping the single best die roll. To this roll, add 2 if a double was rolled, 3 if a triple was rolled, etc. (regardless of whether these were of the same value as the highest die roll or not). If the result is equal to or higher than a target difficulty number (or an opponent's result if in an opposed action) then the character is successful.
After each adventure, a player character may add 1 to one of their attributes.
