From game files: add "gain Potency Up for 1 turn at the beginning of each encounter" Jedi allies have +25 Speed and gain Potency Up for 1 turn at the beginning of each encounter.
Whao... "Jedi allies gain Offense equal to 5 times their speed". So a 250 speed QGJ would basically gain 1250 offense (flat). Thats a 50% increase in base offense. I assume this works additively with other combat buffs e.g. offense up? Otherwise this can scale out of proportion very quickly. This is a pretty huge increase in damage especially from the guaranteed evade -speed up.
