LOL!!

I'm not sure I'm comfortable with the idea of invoking your own consequence for a positive outcome
On the other hand, I'd be okay if you also ended up creating a maneuver on yourself with the aspect Wincing And On My Ass that can be freely tagged by your foe.

Just when I thought I had the whole invoke for effect vs Compel down pat....

Can someone please explain how Entanglement works on page 293.

All it does is place a Bound In Place aspect on the target, and adds one point to make it last the entire scene.

So if this was cast on V what happens on V's turn? Can he move? Does the aspect by itself lock down the target. Does the GM compel it? if so can the target buy himself out of it? Does the caster need to burn an invoke for effect to make it work?

Well, first off, the spell description itself clashes with the rules. You can't make an evocation maneuver last an entire scene.

This one's a bit tricky as it adds an Aspect. You could, in principle, compel that aspect to prevent your foe from changing zones, but that could end up costing you more than a few Fate points over multiple exchanges. Or you could tag that Aspect for a reroll or +2 to actions against that foe that would normally be defended by Athletics (which is pretty much all of them).

Generally, a block is intended to create a hindrance to one specific action. A grapple is a special case and, the way it is written, I'd rule that it could only target a single person or creature and would tie up your own action in the process. A long duration block to all actions to an entire zone would indeed be significantly overpowered.

Remember, even the Orbius spell is a block against breathing that could cause someone to suffocate and pass out. Nothing about the spell's description claims that the person under it's effect can't do any other action, like shooting at the caster. Now you could call it a complete physical grapple, but notice that the grapple rules state you need to tag an aspect first to establish the grapple, so the spell is clearly missing something ... i.e A maneuver creating evocation the previous round.

In the Invoke For Effect/Compel argument, that does indeed look like a compel. I wouldn't allow tagging for that as it's too strong. Now the GM himself could claim that the NPC passed out from his wounds and quietly write down that this NPC has a Fate point to use in the future should he survive.

As for Mental attacks, it is indeed skirting dangerously into 4th law territory due to one simple fact: mental consequences are almost always psychological scars that last a while and generally compel someone into either following specific actions or denying them others. For example, you could blast him with a mind-crushing wave of fear. If they survive, they could get stuck with moderate or severe consequence of The Bogeyman Is Real And He Is After Me, and hence be naturally paranoid and constantly looking over his shoulders. You could try to narrate it with your GM that you are casting a sleep spell who's effects only last the scene and should not inflict any consequences, but even there it's a hard sell.

Although in the latter case, you could cast it as a maneuver, defended by Endurance, that afflicts someone with the Sleepy aspect as a *physical* effect rather than a mental one.

Gotcha.

And I found something, although not sure if it's really an error or if these are more like non-rigid guidelines used during character creation.

In the Power Level list (page 53), 'Feet in the Water' and 'Up to your waist' have skills capped at Great. In the Skill Packages chart (page 65), it offers suggestions that include purchasing Superb skills at the 20 and 25 point power levels.
