For a superhero game I run, I came up with rules for a character who wanted to duplicate themselves. They could probably be tweaked for a rapid summoner, character with a psychic link to golems, or something similar.
Duplication
Costs: 3 refresh
You have the ability to create a duplicate of yourself. Choose an open consequence slot. Your duplicate has a number of stress boxes equal to the value of that consequence (so 2 for Mild, 4 for Moderate, 6 for Severe). If the duplicate is taken out, you take a consequence equal to the value of that duplicate. All of your and your duplicate’s skills are reduced one step on the pyramid (to no less than Mediocre) while it is active. The Duplicate’s high concept is “Copy of …”. Other than the above, the duplicate has the same capabilities as you (but it cannot create a duplicate of itself). Creating a duplicate takes an entire turn. You may reabsorb your duplicate on your turn so long as you both are in the same zone, and doing so takes an entire turn.
Extra Duplicates
Cost: 2 refresh, requires Duplication
You may create additional duplicates. Choose another open consequence slot and reduce your skills and additional step on the pyramid for each duplicate created (to no less than Mediocre). You may create or absorb as many duplicates as you want in a single turn, but the action takes your entire turn.
Mob of Duplicates
Cost: 3 refresh (if you have Duplication, this only costs 2 refresh)
You may create a mob of duplicates, creating one Duplicate for each open physical stress box you have. You may take a consequence to create additional duplicates, gaining 2 for a mild consequence, 4 for mediocre, and 6 for severe. Each character in this mob (including your “original”) only has one stress box and your skills are reduced by one step for each duplicate you control (to no less than Mediocre). Consequences already taken may be used by any duplicate in the mob. This power may not be used at the same time as Duplication or Extra Duplicates.
Competent Duplicates
Costs: 2 refresh, requires Extra Duplicates or Mob of Duplicates
When creating duplicates, any skill you have Fair or better may not be reduced below Average rather than Mediocre.
Things to consider:
-I'd probably go for a "Modular Abilities" like power for amount of refresh summoned allies can have if you're not doing a direct copy of yourself.
-Allies with different skills than you are probably more useful more often than ones who just have a copy of your skills.
-I'd probably switch the physical stress with mental stress for a magic based power like this.
-I would let this be done with Thaumaturgy, but would charge FP (or open tags) for it, like a temporary power.
-This probably need much more tweaking.
No, I would not like this particular group of powers, or tweaks derived from them posted on a resource board, partially because they were really written with Fate Core in mind.
