Based on (Different Attribute), Own Roll

Based on (Different Attribute), Own Roll (PU4 p 12) aka BODAOR is intended to substitute one of the three non-ST attributes (or IQ's two secondary characteristics) names in the parenthesis. For example:
*Based on IQ, Own Roll
*Based on Will, Own Roll
*Based on Per, Own Roll
*Based on DX, Own Roll
*Based on HT, Own Roll
The Power-Ups writeup is based upon a new option for Based on (Different Attribute) introduced in pg 100 of GURPS Powers, though it was not given the ", Own Roll" nomenclature at the time (much like Blood Agent, Reversed wasn't either)
Instead of altering the target roll of a target's resistance, it alters the target roll of a user's activation.
P100 omitted ST (a classic option of BODA which remains legal) and reiterated the five other options. PU4 by comparison explicitly notes how ST was intentionally left out.
Ready literally "shifts the roll from the usual attribute or secondary characteristic to a different one" might actually be interpreted to shift it to something like FP or Basic Speed (derived from HT and DX) or even ST-derived ones like HP or Basic Lift since these are ALSO a secondary characteristics, but "a different one" is likely implied to mean only to one of the two listed secondary characteristics (Per and Will, based on IQ) and not any of the ones which were not listed. Per and Will are generally the only two secondaries which 3d checks are made against: there has never been an example of that being done for BL/HP/FP.
Additional options might become available if using GURPS Thaumatology options of inventing new secondary characteristics for magical purposes.

*Attribute Substitution a perk
*Hard to Use which like Anti-Talent can be used to penalize checks
*Requires (Attribute) Roll which can be used to introduce such checks in the first place for abilities which lack them
*Reliable which like Talent can be used to add to checks
