Passive abilities

GURPS Powers page 153 explains:
:If it requires a die roll, the owner or the GM must roll – there’s no opting out
:effects that apply constantly, or that activate without the owner’s input in a specific situation
:the Active Defense limitation shifts Damage Resistance from passive to active. 
P160:
:The GM may permit extra effort for certain passive abilities, too; e.g., DR with Force Field (extra effort increases DR)
:He might also allow it to enhance passive abilities for a Power Block (p.168)
GURPS Psionic Powers 33 under EK Shield (Damage Resistance with Requires (Attribute) Roll) says "This is a passive ability"
