According to the information that I've seen, Hutts gain a detrimental ability called Awkward which adds Setback dice to Brawl, Melee and Coordination checks. This ability is listed in each of the NPC write ups for the Hutts in their sourcebook, and also mentioned in the descriptive text for the Hutt armour. The number of Setback dice gained seems to vary based on age.
However, the Hutt species seems to gain only Ponderous (one Maneuver to move per turn and no more), but Awkward isn't mentioned. Does this mean that Hutt PCs don't gain Awkward? Where is that particular ability listed, so I can get a rough idea of how many Setback to apply to each Hutt based on their age?
