Flying into a Wall of Force effects?

[Shalewind]

Actually I've seen plenty of people walk into a glass door and get a nice bump so I imagine that a creature moving faster than a man sprinting and slamming into a wall of force would be signifigant, not negligible. Especiall if it was a big creature with a lot of mass.

I've seen video of cars dropped from 40 ft too and that's only 4d6 damage in DnD. No offense intended, but this type of thinking and real life physics don't really have a place. Yes, a drop from a forty foot building will kill just about anybody 50% or more of the time... And slamming into a wall at 10 MPH isn't fun either, but this fantasy... Best regards.

so would a person with "see invisibility" see the wall? I would think ot would fall more under detect magic, the wall is not really there, it is a magic force.

By the rules both would see it (well, detect it in the case of Detect Magic). But in my game, at least, you're right.

We always allow see invisibility to see force effects, including shield spell. I imagine it like seeing the outline or a slight warping in ther area of the spell. Perhaps with a little color.

The fact that you'd imagine it does not mean that it would be so. Not if you want to maintain consistency with falling damage (which is, as Shalewind points out, very forgiving). But you certainly could always tell players that the creature got a nice bump. Or be wildly inconsistent and assess huge damage.

And in fact there are rules for creatures regaining their strability after losing it while in flight listed in the DMG, I just dont have the page numbers handy at the moment. Pretty sure they are near the descriptions of the different types of maneaverability.

Like I said already. You use the creature's maneuverability rating to see whether it can maintain flight when its forward motion is arrested. I think we've established that fairly clearly.

So, yes, I agree. Or you're agreeing with me. Or something. It's a little hard to tell whether you know you're agreeing, the way you put it. But nobody's keeping score.

Oops. Double post.

Another thing to consider is the manner in which the victim is flying. A creature flying vertically won't be so badly hurt. A creature that hits a wall HEAD FIRST will take a LOT of damage. Probably.

Luckily, there is no facing in D&D, nor are there hit locations, so they hit the wall neither head first nor tail first.

falling damage with dr. But. When in space is he casting WOF. So I would give the creature a chance to turn if there was a logical reason. Ex. Party scattered Dragon targets theif which pulls him to the left. Result is clipping the wall. As a dm I would have the Player writing down on a post it where he posting it. Then Track the dragon.

Second I really don't like casting WoF in the air because the next step is
Player Cool Drago slides down the wall. I cast a sphere of WoF around his head. No breath weapon and instant stock and locks.

Well, here it is. I don't like having to apply physics to this game, but I went out and found some formula for a free falling body using earth's gravity. Assuming that my fantasy world as the same gravity and air resistance, here's how it looks. (Not sure if it will line up correctly here)

Sorry for the lenthy post, but it's alot of information. What do you guys think? It should just about be in the house rules section since there is no hard fast rule about it in the books.

It didn't line up nice, so, I'll send the excel spreadsheet if you request it. Let me know if you are interested. Thanks!

Basically, the bottom line, like LokiDR said, use 1d6/30' of movement speed. It simplifies it.

It also makes it grossly inconsistent with falling damage.

Here's a much simpler version, which is also much more consistent: If they're going really fast (like, at least 150 feet per round) then damage is 1d6. Otherwise it's nothing.
