Maledictions w/ No die roll required - is this legal?

[JCurwen3]

If you add Cosmic: No die roll required (+100%) to an ability that has Malediction, what happens? Yes, I know it won't remove the resistance roll! Bear with me on this...

The rules exclude it for:

1. "abilities with effects based entirely on margin of success"
   and also
2. "resisted abilities as Mind Control and Maledictions"

(p. P101 - my emphasis added in bold).

Now from reading that, I'm sure the knee-jerk response would be "read it, it says not on Maledictions". Hence this question - read on please!

I know you'd have to add Fixed Duration (+0%) from Psionic Powers, p. 21 to any ability (like Afflictions) that use the MoS to determine duration, which effectively makes the MoS totally irrelevant (hence point #1 is not a factor).

Now the next thing is that it's excluded for resisted abilities (point #2). And I get that. But there is one RAW way to eliminate the resistance roll - namely, that your target willingly chooses not to resist (for instance, for a beneficial Affliction), in which case it's not a Quick Contest and a resisted ability, but an ability that (by default) is based on Will. Is it legal (and if not, why shouldn't it be?) to have this Cosmic on the ability to remove the need to make your Will roll in these cases where it isn't being resisted?

I've always house-ruled it that way, because it seemed so completely devoid of abuse potential. But I'd like to know if it's technically GURPS legal, and again, if not, why not (pitfalls)?

And, as a related aside, let's say you did your Quick Contest - shouldn't this Cosmic be allowed on the ability such that a failed roll on your part becomes a minimum success (which may or may not still win you the Contest)?

From GURPS Psionic Campaigns (p. 26):

Even resisted abilities may have this version of Cosmic. However, when using them, the psi must still roll against the controlling attribute (or skill) to determine his margin of success for the Quick Contest. If he fails the roll, the ability still works, but treat his margin of success as 0.

So, the user can decline to roll and just go with zero if he wants, right? And then the Fixed Duration takes over? And without Fixed Duration, for wanted afflictions the victim can still roll to beat their Will and get that much duration?

It's still a Contest, meaning that whatever your MoS, the defender has the chance to tie or beat it.

Unless you use the beneficial afflictions rule from powers, where the "victim" can decline to roll

[PK]

For a beneficial Affliction, the combination of Cosmic (NDRR) and Fixed Duration will accomplish the result of, "I use my ability and it buffs my friend for X minutes," yes.

But just to be clear, for a standard, hostile Affliction, the combination of the two means that if the attacker either fails his roll or declines to roll, his MOS is treated as 0, which means that the victim is very likely to defend successfully against it. If the victim still manages to fail, the ability afflicts him for a fixed duration of X minutes, regardless of the actual margin of victory.
