GURPS Powers and Enchanting

[weby]

A few notes on the excellent list by whswhs:

Biological powers: In some settings/some of the powers may be transferable by things like blood products for temporary(until they decay) or permanent(it is an infection) effect. In those cases the counter is to neutralize the effect with something that removes the transmitted thing, like if it is a disease you need to kill the bacteria/virus.

Divine powers: Expanding on the prayer comment: In some settings it is very common for holy men to bless others granting them temporary powers and in some they may temporarily transfer their power to others. All that happens true prayers. Neutralization is normally through praying to an opposing god of the original granting them. Also champions of opposing gods may have neutralize powers.

Psi powers: These are neutralized by other psi powers and/or Psi technology.

Sprit powers: in some settings someone can direct the spirits to possess or help a willing or unwilling target. Neutralization is often though Exorcism.

Super powers: Some super powers are gadget based and there have been cases where someone has stolen the power object of some super and used it.

More generally, every power source provides its own distinctive ways of gaining powers, granting them, countering them, and embodying them in objects.

And even that has an exception: none of these is possible at all with the Cosmic power modifier, at least by any ordinary means. (I suppose you could take Neutralize Cosmic with some level of Cosmic enhancement and allow it to disconnect your foe from the primal energies of creation, but straight Neutralize Cosmic simply wouldn't work.)

Anyway, what you need to do is study the power modifier and the rationale for it. Power modifiers aren't just trivial flavor differences in an underlying generic "I haz powerz" quality; they're different ways of fitting abilities into the game world.
