Going with my sense of plausibility, I'd say You need to know with how much force the water pushes in (so, pressure and area), multiply it by earth's gravitational pull and You get a mass… But that's ridiculously unplayable. I'd borrow and reshape the limits on gases to say You can stop a circle wall with a [level] radius, but that seems too cheap. The quickest way I can think of is to figure out the mass of wood or steel "removed" by the ram and use that amount of water. Still a drag, I'm afraid. 2. I don't think so. You can impede someone's (or something's) movement, but You can't move anything indirectly. 3. Generally, I'd say you can slow it down or make it faster by the value of speed determined by Your level of Control. 4. I'd say no, as it isn't telekinesis. I'd say you can bend them slightly, making their flight less predictable, giving Your foe a penalty to hit You, as per Getting Tricky. 5. You don't need to keep that string, even. You only need touch to establish control, not to maintain it. __________________ My irregular blog: d8 hit location table

In many cases it depends on the genre of the game you are playing. However, my answers would be, 1) No idea. My first thought is 10 levels, but a a 6ft by 6ft by 6ft square hole would be 2x2x2 yards, so if you could control 8 cubic yards of water I'd allow it. 8 cubic yards is about 13,484 lb. That would require 11 levels of control. So, ya, 10-11 levels should be allowed to do that. Depending on the genre I may allow someone with as few as 8 levels, but probably not less than that. 2) I disagree with Gnomasz here, by definition you almost have to be able to do this. If I have Control (Air) moving the air I control by definition means I have to move the air that it is moving through out of the way. That's what I figure anyway. 3) In theory you increase/decrease its speed by the amount you can move it. If it is the same material this kinda works, but this does not really work when you are slowing other things. For example moving air past someone at 6 yards/second is not going to slow them to a stop if they have a speed of 6. You could do some physics calculations, but that is too clunky...hmm... 4) No*. Lets say an arrow flies at about 100 yards/second (this may be way off). If you have control (wood) 100 then, sure, you should be able to do this by just droping it's velocity to 0. With more likely levels of Control, say 2-5, no you just can't effect it's speed or trajectory fast enough. As pointed out by Gnomasz though, you should be able to give something like -1/level to their shot and maybe damage. 5) I think Gnomasz is right. __________________ The person who says it cannot be done should not interrupt the person doing it.

I ended up deciding that it would be a power block, so each level of power gives 1 DR of slowing the projectile down (and requires the spell to be ready since it's sorcery). I like the idea of giving either -1 to hit per level, or 1 DR per level depending on if you are bending the projectile, or matrix trying to stop it dead.

Can you use control to make a surface that holds back the rest, instead of controlling an entire amount of the material (A balloon of controlled material to move other stuff around)? 3. The speed of your control is given in an absolute Level yards/sec. What happens when you use control to force something against something else? 4. If I have control (wood) and an increased range enhancement, can I use that to deflect arrows before they hit me if I'm prepared? 5. How much of the material must you be in contact with to Control it? Could you leave a very thin string of the material leading away from the main mass to you so you can control it at a distance?
In this case I would rely on #2 to answer #1.
How fast is the water rushing in? You need that much Control to stop it, less slows it down. That is a simple way to handle the mass and pressure.
Mostly this would be an eyeball it kind of thing in play.
But once you sealed the hole Control would be a great bilge pump.

Moving something else is more like a shove or slam, so based on Mass and possibly ST.

Power Block or Parry are good choices for the Arrows.
If your fast enough and can do it at range a tiny bend in the arrow is going to throw it off course. However I would let Control act as a Power Block even without range.
The bullet stopping power of Neo in the Matrix should be doable with Control IMHO. See Power Block in Powers for details.

If I were doing this one I'd equate Control to Telekinesis to ST.
