No Countermeasures

GURPS Powers 21:
:No Countermeasures
:Powers that face no countermeasures except those that affect the wild versions of their abilities add +0% to their power modifier. This is the “default” situation; it applies to any
power that can’t claim a limitation under Mundane Mountermeasures or Anti-Powers.
:Example 1: It’s traditionally impossible
to neutralize chi powers.
