=>Attempt to filter "Powers that alter the bearer's personality" (immediately/persistently/forcibly, as a consequence of the functioning of the power; obviously having powers of any type is going to change you over time and that's not predictable or likely to be filterable)
==>"...except where compensated for by other powers in the same cluster."
==>Mark them with a red X.
=>Attempt to filter "Powers that impede the bearer's cognitive or perceptual abilities" (again, directly by screwing with your brain/senses; don't filter a power that makes walls just because it doesn't let you perceive through walls)
==>"...except where compensated for by other powers in the same cluster."
==>Mark them with a blue or green X.
=>Attempt to filter "Sentient powers"
==>Attempt to filter "Sentient powers that can communicate intelligibly with a human bearer immediately on or soon after acquisition."
==>Attempt to filter "Sentient powers that can independently (use | modify the usage of | prevent use of | hinder use of | alter side effects of using) the power."
==>Attempt to filter "Sentient powers that are capable of (influencing the bearer other than by communicating with them | ASSUMING DIRECT CONTROL of the bearer)."
==>Attempt to filter "Sentient powers with personalities Progenitor finds particularly amusing/interesting."
==>Attempt to filter "Power clusters with >1 sentient power" (oh god shard drama...)
==>Devise some kind of marking system for all of these, possibly involving colored asterisks.
===>If successful, maintain these filters through all future steps.
==>Compare the "Emissary" and "Aberration" clusters that appeared when searching for powers with secondary and tertiary powers to the "Emissary" and "Aberration" powers and/or power-clusters that appeared when searching for powers of parents.
===>Subtle differences in the central power, if any
===>Differences in the associated secondary and/or tertiary powers
====>If found, search for "All powers designated as 'Emissary' or 'Aberration' and/or power clusters centered on 'Emissary' and/or 'Aberration'" and compare available sub-power sets.
===>Search for "The three powers with the greatest number of discrete power-clusters centered on them" and then for "The power-clusters centered on those three powers"
===>Search for "The three powers most commonly found as a secondary power" and then for "The power-clusters including those power(s), ordered horizontally by color and vertically by strength of the central power, highlighting any clusters that include two or three of the most common secondary powers"
===>Search for "The power cluster with the highest additive strength of the central power and its sub-power(s)" and "The power cluster with the highest multiplicative strength of the central power and its sub-power(s)"
===>Search for "The top and bottom five power clusters by ratio of the strength of the central power to the strength of the strongest sub-power"
===>As previously, but comparing the central power to the additive total of the subpower(s), if more than one are present.
