Orbius is specific in being adjudicated as a grapple.
Grapples are blocks against (almost) all actions.
Orbius is, thereby, specific in being a block against (almost) all actions.
But then, we've been over this before. You have your interpretation; I have mine.
Dandy, so you have to recast it every exchange the same as a physical grapple. Adjudicated as a grapple... Oh, and you'll be using Might rather than Discipline. Adjudicated as a grapple... You won't be taking any other standard actions while maintaining it either. Adjudicated as a grapple...
See how nifty it is when you can directly contradict something you don't like about a spell with that phrase?
You must be specific + being specific is not likely meant to be
directly contradicted by a later vague statement.
If you want to write a
different spell that blocks all actions and grapples, by all means. You'll need to rewrite the description though. Hell, you could even call it Orbius. Orbius as written is not what you want though and I've got extremely solid ground to say it was not intended to be interpreted to as such from both canon and RAW.
A few disordered points:
1. You can't take someone out with a normal block. If Elaine's air shell took Harry out, it was an attack inflicting stress. A 100000 shift block with 10000000 exchanges of duration won't take out a pixie.
2. If you can immobilize an opponent for 8 exchanges, you've either won or had no hope in the first place. The stress inflicted by Orbius is just not that significant compared to its ability to block everything.
3. There was no typo in my earlier example. 8 shifts base, take mild mental and tick off 4th mental stress box to get +5 power. Eat 5 points of backlash, taking a mild physical and filling in 3rd physical stress box. 13 shifts.
4. Wish I had my books on hand to check out this zone block stuff. I was under the impression that evocations of all kinds could be made zonewide for 2 shifts of power.
5. I have no idea what the "resisted by Endurance" thing in Orbius's stats means. As far as I know, blocks are never resisted with anything.
Ahh, didn't see where you were getting it from. And yeah, its primary usefulness is in the all-actions block that directly contradicts the spell description.
As for resisting? I think that was a bone thrown in to mitigate the vileness a bit.
The zonewide for two shifts thing is a general rule for spells. Blocks have their own specific way of dealing with zone-wide-ness though. This is why I store my pdfs in my Dropbox Private folder. Always have them wherever I go and there's case law giving me the OK copyright-wise.
Heh, 10000000 exchanges of duration on a pixie will likely result in you being taken out by old age while the pixie twiddles its thumbs. Pixie: 1 You: 0
