Re: Multiform for Free? Frustrated....
Multiform is an interesting power in that it has had 3 different implementations, none of them entirely satisfactory.
Several proposals earlier in the thread are reminiscent of Multiform as originally introduced in "Champions III": All forms pay 1/10 of the total cost (excluding the multiform cost itself) for all forms.
Complicated enough at the beginning, the math resulted in a maintenence nightmare as experience points were added to the character.
The last time I spent some concentrated time thinking about this (years ago), I concluded that the only "clean" way to implement Multiform was to declare it to be a "character framework" instead of a sort of power framework (I know, technically it's a power today) -- and maintain a completely separate "multiform character sheet".
Back in those 4th edition Champions days, I worked up a version with a cost structure derived from multipower.
Revised Multiform:
The Experience Reserve works just like the point reserve in a Multipower: It can be shared among all your forms. It represents the maximum total free points (Base Points + Experience) that is available to each Multiform slot.
The slots work only slightly differently than a Multipower. For each form, you must pay 1/10 the maximum total points (including disadvantages) that the form can have. Up to that maximum, the form can get free points equal to the Experience Reserve. Once you use up the points in the reserve, you can start taking Disadvantages as long as your (total cost)/10 doesn't exceed the slot cost. Of course, just like any other character, the Game Master has the final say on the maximum total cost, and maximum points from Disadvantages.
Example:
Greymalkin, a wizard who can assume the form of a panther, is a starting character in a 100(base)+150(disads) superheroic campaign..
Since he has no experience (yet), he has only 100 points to spend on his Multiform.
60 Multiform Experience Reserve
20 Wizard form, up to 205 points total (60 free, 145 from disadvantages)
20 Panther form, up to 205 points total (60 free, 145 from disadvantages)
Greymalkin's two forms each have 60 free points, and can raise their total cost to 205 with disadvantages.
Experience points get spent on the worksheet rather than on the characters directly.
I was ultimately dissatisfied with this because like multipowers generally, it favors slots with similar costs. (You can buy a slot to less than it's reserve points, but the savings are miniscule.) I wanted a structure that would encourage creatively different forms. It also seemed more expensive than it should be if you wanted to have many forms (a la "animal man").
So I worked up a VPP equivalent that would allow infinite forms -- but this had the problem that there was no benefit (mechanically) from building a form to anything less that the maximum power.
Even though I haven't played in some years, Multiform still tantalizes me with the notion that there is an elegant solution to be found.
