There's an underlying problem here that isn't just about doorways and line of sight, but is about group communication and the right to play a game you enjoy (or leave). The game is not what is in the books, but what all players and the DM want. The best way to spoil a session or a group is to strictly stick to the rules contrary to what everyone enjoys. A DM ...

There is an argument to be made that longbows' range already assumes parabolic flight when possible. If you buy that idea, there is a built-in rule for handling the difficulty of attacking targets that are out of sight: Concealment. See the Player's Handbook v3.5, p. 152, or total concealment in the d20 SRD. Because you have to target a square where you ...

According to d20srd: Line of Effect A line of effect is a straight, unblocked path that indicates what a spell can affect. A line of effect is canceled by a solid barrier. It’s like line of sight for ranged weapons, except that it’s not blocked by fog, darkness, and other factors that limit normal sight. You must have a clear line of effect to any ...

In the first case, it is clear that the attacker has line of sight. The attacker is totally unobstructed from the target. In the second case, the attacker does not have line of sight, and cannot attack the target with a sight-dependent attack. The attacker could, however, move to the side, which would allow them to attack the target (whou would have ...

Range: Personal or targeted at yourself Cast normally Has a Target entry You must be able to see or touch the target, and you must specifically choose that target. When blind, your only solution is to touch the target. If you are the target, this is automatic. Otherwise, the Invisibility entry of the Glossary provides an option when the location of ...

If you decide to stay with this DM and he doesn't want to change his style, might I suggest a few ways to: Exploit the "Rules" This isn't really a "rules" issue, it is a play-style issue. The participants will either adapt to each other, or the game will end. Here's some tricks to leverage these new game mechanics: Turn the rules back on him: Have the ...

No, Bursts DDI do not go through walls. Because: A burst affects a target only if there is line of effect from the burst’s origin square to the target. A line of effect DDI is A clear line from one point to another point in an encounter that doesn’t pass through or touch blocking terrain. Walls are the first example given for Blocking ...

Yes, You do not need Line of Sight unless the spell specifies it (Rules Compendium pg. 106). Magic Missile DDI does not have this restriction. The wizard must have Line of Effect to the target creature though.

You need Line of Effect to "effect" creatures. This is true for Aura's The aura fills the creature’s space and each square that is both within a specified distance of the creature and within line of effect of it. Blasts A blast affects a target only if the target is in the blast’s area and if there is line of effect from the origin square to the ...

Yes, you need Line of Sight. One other difference from movement is that you can teleport while immobilized, restrained, or grabbed. From the PHB3 definition of teleportation Destination Space: The destination of the teleportation must be an unoccupied space that the target can occupy without squeezing. If arriving in the destination space would cause the ...

There are no explicit rules that require this style of play, and there is a substantial body of rules that are implicitly contradictory. (There's nothing explicitly against it because it's so contrary to the history of how roleplaying games are played that no designer has ever needed to say "don't do this." There is also a lack of rules about not eating the ...

Heroes of Battle, pages 68 and 69 talk about volley fire and indirect fire. While researching longbows recently (for the sniper article) I found an excellent quote from wikipeida: The longbow had a long range and high accuracy, but not both at the same time. Most of the longer range shooting mentioned in stories was not marksmanship, but rather ...

From the Compendium: • Destination Space: The destination of the teleportation must be an unoccupied space that the target can occupy without squeezing. If arriving in the destination space would cause the target to fall or if that space is hindering terrain, the target can make a saving throw. On a save, the teleportation is negated. ...

From the compendium entry on the area keyword (used in Scorching Burst) You choose a square within an area attack’s range as the attack’s origin square, which is where you center or start the area of effect. You need line of effect from a square in your space to the origin square. For a target to be affected by an area attack, there needs ...

From my reading of the PHB, both require line of effect from their origin square, and neither require line of sight (p272): A blast affects a target only if the target is in the blast’s area and if there is line of effect from the origin square to the target. and A burst affects a target only if there is line of effect from the burst’s origin ...

In 4E, teleports require line of sight, but do not require line of effect. You could teleport through a glass window, no problem. So, in general, if a power gives you line of sight where otherwise you would not have it, the answer is "yes, you can teleport there". That is provided the distance teleported from your location does not exceed normal ...

Blindsight notes that: A creature that has blindsight can clearly see creatures or objects within a specified range and within line of effect, even if they are invisible or obscured. The creature otherwise relies on its normal vision. Stinking cloud: The burst creates a zone of poisonous vapor that blocks line of sight until the end of your next ...

Yes, but quirkily, by RAW you can't teleport there. The compendium entry for BlindDDI says A blind creature relies on special senses, such as blindsight or tremorsense, to see within a specified range Neither it, nor the blindsight and tremorsense entires mention line of sight specifically, but I think being able to "see" should grant line of sight. ...

Apart from RAW, I'd say it's much more climactic if effects such as you describe are discovered during combat, and not in the previous DM narration: "You shoot an eldritch blast against the kobolds on the other side of the room. The blast reaches half the distance, and suddenly stops against a glimmering wall" against "You can see a glimmering ...

That would make intuitive sense, but D&D 4e dispenses with intuition in favour of tightly-defined, interlocking rules that do all and only what they say they do. In this case, we look at the definition of "obscured square". The only effect of obscured squares is to grant concealment (Total Concealment in this case, of heavy obscurement) to targets in ...

Line of Sight is self-apparent: if the PCs can see the enemy, they have it. In most other cases, cover should also be obvious, e.g. the enemy is hiding behind a rock. As for your hypothetical invisible wall of force, I assume you have a specific encounter in mind. For a specific encounter, pretty much anything goes. A special, magical (duh) wall of force ...

Most wargames and a few RPG games use a scatter diagram and relative degree of success to represent indirect fire. Basically you are at a minus (sometimes considerable) when you roll you are seeing if you hit a designated area. If you miss you still hit an area but at some distance from the target. For d20 based systems I recommend assigning an addition -3 ...

In the diagram shown, a blast 3 power would not effect either of the targets there is nowhere to start a blast that would reach them. However, were the character to move up one square they would be able to use the top right corner as the start of the blast and actually effect both targets with no penalty. There are two reason for this. The blast would not ...

Teleportation does not require Line of Effect, but Line of Sight is still necessary. In your example, the Eladrin would only be able to teleport to the previous room if the wall he was backed up against had a window. Other notable differences from normal movement are: Does not provoke opportunity actions. Unhindered by objects or terrain in the path of ...

I believe the use of a mirror should allow for establishing line of sight. However, line of effect is more the issue here. Most any attacking power requires line of effect to the target, or (for burst/blast effects) requires line of effect to an origin square from which there is line of effect to the target. Especially, consider the verbiage noted in ...

It's not RAW, but I will note that a 1 foot square hole in a wall gives spells line of effect. "An otherwise solid barrier with a hole of at least 1 square foot through it does not block a spell's line of effect. Such an opening means that the 5-foot length of wall containing the hole is no longer considered a barrier for purposes of a spell's line of ...

You mean the "Divine Ward" feat from PHBII, that lets you extend a spell from range Touch to range Short when you target the guy you're warding? I had a cleric PC of mine take that once. I'm not sure what you mean by "you needed to touch the person in the first place". You mean "the spell used to be range Touch?" I don't think that's directly relevant. ...
