When Drift travel caused the thasteron market to crash, some mining conglomerates sought new uses for thasteron that would sustain some of the diminishing demand. One of the more successful ideas was the Vellsencraft Ltd. thasteron-fueled augmentations, spurring the thasteron-punk subculture that embraces the antiquated aesthetic. This modification is limited to arm, hand, leg, foot, and spinal column cybernetics. The augmentations appear to be made of copper, brass, wood, and leather, featuring tiny fueling ports and gas vents, and the faint exhaust gives you a –2 penalty to Disguise and Stealth checks except in environments where the smell would be innocuous, at the GM’s discretion. Vellsencraft augmentations cost 20% less than usual, but they consume 100 credits’ worth of thasphalt (page 50) to keep functioning.
The concept of a Steam punk image for stuff is rather interesting but the limitation of it costing Thasphalt doesn't say how frequently I would need to feed each item their 100 creds fuel. If we are speaking of daily, then the costs can rapidly outweigh the benefits (Till later levels).
So could the limbs still work as basic if I don't feed it or would an X legs user be resigned to using his boring spare legs during travel?
Generally assuming its 100 per graft (Understandable), would it be a standard, move or full action to feed said graft?
