Lucas (Fallout 2)

Lucas/Standing Fist is the Chosen One's fellow tribesman from Arroyo.

Speak to Lucas in Arroyo and he'll offer to train you in unarmed combat if your agility is at least 6. This will raise your Unarmed skill to 40% if it's below that, otherwise to 55%. If your skill is already at 55% or higher, there is no bonus. He also carries a bag of Healing Powder, so if you want to barter with him for it, do it before receiving the training.
