[FT] Reasonance Weapon

Looking back over the Resonance Field Generator in the WDA, Its a nice concept
(IMO, but far too complex in application, and hard to balance. Here's another
version.

Resonance Field Projector:

A ship may only fire one RFP on any given turn (though it may mount more than
one) Each ship with an RFP targets a point in its firing arc (max range 24 MU)
when activated. At least 2 RFP's must target the same point for the effect to
begin. Mark the target location with a die or counter indicating the number of
converging RFP's (increment the number for each RFP added over the course of
the combat phase).
At the end of the combat phase - after all other fire has been
resolved, determine RFP effect: Area of effect = radius in MU equal to number
of converging RFP's
Damage = All ships within area of effect take 1-number of converging
RFP's damage in beam dice. Rerolls apply, but reroll damage does not
penetrate armor. Screens/shrouds work as normal. Fighter
groups/missiles in area of effect take the same number of dice, but
suffer losses of 1 missile/fighter on each 5 or 6.

Possible additional limitation: No other weapons (from a given ship) may fire
in the same arc as the RFP. Possible additional limitation: RFP can only be
fired every other turn.

My feel for this is that the RFP should cost on the order of a class 2
beam. Its power does not scale linearly, though - multiple converging
RFPs are much more powerful than the equivalent mass of class 2 beams, but
there are other inherent limitations
