Attribute Substitution

†
You've trained a skill to use an attribute other than its usual controlling score. The GM decides what to allow, and the change should make sense. Some guidelines:

DX-based skills with a complex technological aspect can shift to IQ ("Battlesuit based on IQ"), while those that involve fine work or hand-eye coordination can move to Per ("Driving based on Per").

IQ-based skills for small tools can go over to DX ("Lockpicking based on DX"), those used to find or follow things can move to Per ("Shadowing based on Per"), and those with a supernatural angle can shift to Will ("Ritual Magic based on Will").

HT-based skills for movement can shift to DX ("Swimming based on DX"), those with a social side can move to IQ ("Sex Appeal based on IQ"), and those for cinematic combat effects or resistance can become Will-based ("Body Control based on Will").

Will-based skills can generally drift to IQ ("Exorcism based in IQ"), and those with cinematic combat effects or that aid resistance can shift to HT ("Power Blow based on HT"). Per-based skills involving hand-eye coordination or fine manipulation can move to DX ("Search based on DX"), and most Per-based skills can shift to IQ ("Detect Lies based on IQ").

This affects routine skill use but doesn’t override a GM- or scenario-mandated roll based on a specific attribute. For instance, if an adventure calls for a Per-based Lockpicking roll, Attribute Substitution (Lockpicking based on DX) doesn't let you make a DX-based roll – you have to make a Per- based roll like anybody else.

You must specialize by skill and attribute, as in the examples. Nobody may have more than four Attribute Substitution perks.
