IIRC, the Tracing custom Power was originally intended to simulate Archer.
TRACING [-2]
Description: You have the ability to project weapons from your mind into reality.
Skills Affected: Craftsmanship, Weapons, Guns
Effects:
Projection. With a supplemental action, you may create a melee or thown weapon out of thin air. Two-handed melee weapons created this way are capped at weapon rating 3, while thrown weapons and one-handed melee weapons are capped at weapon rating 2. Weapons created this way last until the end of the scene or until you make a new weapon.
Reinforcement. By spending a scene and making a successful Craftsmanship roll, you may cause your projected weapon to become fully real. This means that it lasts indefinitely.
Versatile Tracing [-1]. You may create simple objects other than melee weapons with this power. Armour, simple tools, keys, and levers are all possible.
Complex Tracing [-2]. (Requires Versatile Tracing) You may create complex objects with this power. Firearms, explosives, chemicals, and machines are all possible, although at the GM's discretion a Craftsmanship roll may be required for certain items. Explosives, firearms, and two-handed melee weapons are now capped at weapon rating 5, while thrown weapons and one-handed melee weapons are now capped at weapon rating 4.
QUASI-MODULAR ABILITIES [-Varies]
Description: You have the ability to alternate between multiple powersets.
Musts: You must "pre-pay" a number of refresh points equal to the total value of each set of powers that this power affects, plus a surcharge of one refresh.
Skills Affected: Varies.
Effects:
Two Powersets. Pick out two sets of powers, each with a total refresh cost one less than the cost of this power. You may use either set of powers, although it takes a full action to go from using one to using the other. The GM decides what is and what isn't a valid choice for inclusion in the powersets provided by this power.
Item Of Power Collection [-0] You own multiple items of power. Design a number of Items Of Power equal to your Resources skill. At any given time, you may use or loan out items with a total refresh cost up to one less than the refresh cost of this power. You do not receive the Item Of Power discount. If you have the Tracing power, then you may summon and dismiss these Items Of Power out of and into thin air. If not, you must treat them as physical objects.
It's not the only way to go, though. If this doesn't float your boat, I'm sure we can work something else out.
