abe, you might want to edit your first post and change the name to "steam power idea" so everyone knows what the thread is about
here's an idea i call "Reese's wonderful elemental rifle" (cause i suck at names

)
cost: 510gp (+200 per extra amplifyer)
assistants: 2 (amplifyers require two assistants)
size: huge (74 + 6 per extra amplifyer)
weight: 26lb ( + 1 per extra amplifyer)
this huge weapon (thank goodness for integrated parts) can be switched between four attack modes:
line, cone, burst, and touch (raw)
and does either 1d6 fire damage (and sets things on fire in one round of continuous contact) or 1d4 electrical damage (with a +2 on attack rolls against metal targets)
it contains enough fuel for 10 shots of fire damage, and has no known limit on the number of electrical attacks (beyond the nessesary fuel to run the steam engine)
the light function sheds light in a 40' by 40' area centered on the device
it can also shed light in a cone 320' long when using the pump, and will blind targets within 80 feet (ranged touch attack vs. opponents eyes, dc16 reflex save, failure = blinded for 1d6 rounds)
billows + pump + lobber + nozzle + amplifyer (multiple) + nozzle + spark generator + pilot light + light generator
suggestions:
removing the light generator will lower the size to large (making it a two handed weapon for medium sized characters) and allow for a second amplifyer without increasing the size to large again
at first opportunity, use integrated parts to lower size, making room for more amplifyers.
order of integration priority: (integrate with anything size 6 or smaller)
light generator (16)
pump (12)
spark generator (12)
billows (10)
lobber (8)
add more elemental generators as designs (and 'integrated parts' uses) become available, as fire, light, and lightning are somewhat limited...
(i can't just throw parts together and wonder what they'll make, 'cause it goes against what they teach in my programming logic classes, i need a purpose if i'm going get my mind to produce anything)
