1) Flaming sphere, PH 232, unclear.
Relevant text: "if [the flaming sphere] enters a space with a creature, it stops moving... and deals 2d6 points of fire damage to that creature."
Question: what about squares containing multiple creatures?
It burns them too. Just because it refers to one creature in the description (largely as an example) shouldn't cause you to think the description is trying to exclude all other possibilities. It's unclear but only if you're trying not to see the obvious.
Also: I'm unclear how to run flaming sphere if line of sight is interrupted, but I probably just overlooked something.
Line of sight (or line of effect for that matter) is not needed except to cast the spell in the first place. After that it moves in the direction you indicate. If you can't see where it CAN go then you simply have to guess where it's moving until such time as it exceeds your range. You may want it to go 20' north and point in that direction, but if you can't see that it's blocked by a wall to the north then you simply don't see that it isn't going anywhere.
Relevant text: "to determine whether a target has concealment from your ranged attack, choose a corner of your square. If any line from this corner to any corner of the target's square passes through a square with concealment, the target has concealment."
Cover on ph150 is the same with one slight change "if any line from this square passes through a square or border that blocks line of effect or provides cover, or through a square occupied by a creature, the target has cover."
a) If the line between two such corners passes along the border of a concealing square, is there concealment, like with cover?
You didn't quote the whole text, or didn't quote it accurately. "To determine whether a target has concealment from your ranged attack, choose a corner of your square. If any line from this corner to any corner of the target's square passes through a square
or border that provides concealment, the target has concealment."
For cover, must the border provide cover, or will the border provide cover if its square provides cover?
Borders and corners are part of the square, they're just used as specific parts for purposes of seeing what crosses a border or intersects a corner. If a square provides cover/concealment then its borders and corners provide cover/concealment.
b) Additionally, if my square is well lit and my opponent’s square is well lit, but there is a square of shadow between us, do they really intend for that to provide concealment?
No. Shadows aren't going to provide concealment to creatures that are not actually in shadows, much less if they're standing in well-lit areas. Yes, p.152 is written to suggest it, but be serious. It's bad phrasing/a missstatement/an obvious error. It's clearly not the intent because that would be clearly daft.
c) But the real biggie is this: it appears everyone in ranged combat gets a cover bonus. When you draw a line from a corner of your square to the farther corners of an opponent's square, you've drawn the line through a square which contains a creature (your opponent). This is sufficient, according to ph150, to provide cover.
Clearly the intent is not that all creatures should be considered to provide themselves cover and concealment. You're correct in that if you take it absolutely literally it's whacked, and for that reason it should probably be errata'd. However, that is so obviously not the intent if you're seriously trying to figure out what the way to handle it is you're either being obtuse or purely argumentative.
3) PH 148 "accidentally ending movement in an illegal space"
Text: "When [a character ends its movement where it's not allowed to stop], put your miniature in the last legal position you occupied, or the closest legal position, if there's a legal position that's closer."
a) <spit-take> This can't be right. In certain circumstances, I can artificially increase my movement an indefinite amount, move through opponents squares without sufferring attacks of opportunity, or maybe even teleport through doors?
You're not quoting appropriately again. First sentence of the relevant paragraph is "Sometimes a character ends its movement while
moving through a space where it's not allowed to stop." The rule is talking about
prematurely being stopped, not about the legality of stopping in the intended destination itself. That's covered at the first full paragraph of the same page where it says, "Ending your movement: You
can't end your movement in the same square as another creature unless it is helpless."
If I tumble in to aid a dying but surrounded companion, administering a potion that moves him from helpless to conscious, I would get to immediately move my miniature to safety?
In your example you would BE in a safe, legal position because your dying companion is helpless and there's no need for you to find someplace else to be. But for the sake of completeness of argument let's suppose your companion was not dying, merely heavily wounded and you wanted to tumble in and give him a potion. The DM who allows you to attempt to do things which by the rules you
cannot do deserves the headaches he gets in trying to sort out the results. BTW, needing to teleport through doors would hardly constitute a "legal position" now would it?
b) Do you really only check to see if someone’s in a legal square after they end a move action?
No. You determine beforehand where they intend to end their move action to prevent them from even beginning to try it, even though they ought to know darn well they aren't allowed to do it.
It might be time for wotc to write up some rules for same sized creatures fighting from the same square when they are allies, or at least when neither is willing to grapple.
The existing rules are sufficient because they don't allow it to happen in the first place, but it's not difficult to make a house rule to allow it if you feel it's needed in your campaign. For example you could consider both characters entangled.
I know it sounds like a huge modification to the game, but the fact is that this situation comes up. And not just in overly contrived ways practiced by the gamebreakingest rules lawyers. What if a medium someone uses enlarge in a 2 square by 2 square room, what happens to him and his opponent? When a black pudding splits (MM201), it might not fit in it's original space (going from medium to small, for example). Where do the new creatures go, do they both stay in the same square and move out of it on their turns? What if they are in a very small room?
1.)It should only be a problem when gamebreakingest rules lawyers are attempting to get away with something, 2.)You use common sense and have one of the two occupants pushed out of the room to available spaces and/or apply appropriate penalties to the M-size creature who suddenly (and stupidly) has turned himself into a size that doesn't fit the area he's in, 3.)the new black pudding occupies the first available legal space next to its former self, or if no such legal space is available it pushes other creatures out in order to make room with all appropriate consequences. If they are in a small room then at least one of them is probably considered to be squeezing into the area.
There may not be hard and fast rules for this sort of thing but it's not hard to adjudicate a solution either without having hard and fast rules.
Maybe this shouldn’t go in the errata; maybe this is just a personal gripe. Eh, either way.
Not errata at least. A little closer reading of the rules, and willingness to do what the DM is there to do - adjudicate in situations that the rules don't cover. Absence of a rule to cover a given situation is not necessarily errata.
