No Signature

==Base ability and variant==
+20% (B106)
In optional extra detail mode +5% per -2 to rolls to notice the ability, and treat -10 (+25%) as “undetectable.” (GURPS Powers 103)
==monster hunters==
Monster Hunters 1 pg 43 applies this to Damage Resistance with Force Field, assuming that DRw/FF is visible by default.
*This April 2011 publication by PK clashes with his July 2016 publication GURPS Sorcery: Protection and Warning Spells which appends the Visible limitation to DRw/FF, assuming it is invisible by default.
==Notes==
In 2008 Kromm mentioned March 25:
:There is no "Extra Defense" advantage that you could then modify with, say, Independent or some other modifier that would make it hands-free. However, you get one additional block or parry per hand, regardless of number of hands or number of attacks, so that's where the solution can be found. Try this:
:Extra Arm 1 (Force Extension, +50%; Shield Mount, -80%) [7]
Force Extension is stolen from Stretching; see Powers, p. 78. In this case, it gives you a visible limb of force that can't be injured.
:Shield Mount is by analogy to Weapon Mount. If being restricted to mounting and using one weapon is -80%, the same should go for any other dedicated-purpose limb.
:You can make it invisible with No Signature, if that's important to you. I don't see how it's worthwhile, but whatever. Since you can always specify special effects for your abilities, why not just say it has the appearance of a glowing shield?
Supporting that an Extra Arm with with "Force Extension" (P78 for the Stretching power) would be a candidate to become an invisible arm for an extra -20% for No Signature.
PK had mentioned in 2007 https://web.archive.org/web/20180122220014/http://forums.sjgames.com/showthread.php?t=29511
:I don't see why No Signature would be legal to take on a Striker. Striker is not an attack power -- it's a body part. You wouldn't let someone take No Signature on Extra Legs and have invisible extra legs from it, just like you wouldn't let someone add Accuracy to an Extra Arm to give them a bonus to their aimed attacks with that arm.
:Attack enhancements are intended for Affliction, Binding, and Innate Attack, along with other Ranged abilities -- not for body parts.
This did not address the "Force Extensions" modification however, where no sig is bought for the extensions but not the base limb.
