Diagonals & Difficult Terrain


Rules Discussion


The following rules confuse me:

"Moving into ... difficult terrain ... costs an extra 5 feet of movement. Moving into ... greater difficult terrain instead costs 10 additional feet. This additional cost is not increased when moving diagonally." (p. 476)

As written, moving diagonally in difficult would still cost just 10' and greater difficult would cost 15'.

*However*, the example side-bar on p. 475 says that Lini would need to pay 15' to move diagonally in difficult terrain (not 10').

Is the reference to not having to pay the diagonal penalty only intended for greater difficult terrain? (If so, that's not worded clearly.)

The sidebar explains it. Every other diagonal move costs 10 feet instead of five feet, so the first diagonal into difficult terrain costs 10 feet (five feet for an odd-numbered diagonal plus 5 feet for difficult terrain) but the second diagonal move into difficult terrain would cost 15 feet (ten feet for an even-numbered diagonal move plus the same 5 feet for difficult terrain).

You still pay the extra movement cost for every other diagonal, but you don't add any additional cost for diagonals into difficult terrain (i.e., a rule that said the first diagonal into difficult terrain costs 5 extra, but the the second costs ten). Or, the terrain costs don't care if you're moving diagonally, but the general rules for diagonal movement still apply.


I believe their intention was to say that the additional movement cost from difficult terrain is not itself increased by moving diagonally, only the original movement speed cost. Basically they are saying that your movement cost is effected by both moving diagonally and difficult terrain, but moving diagonally and difficult terrain do not effect each other directly. They only modify your final movement cost.


Okay, thanks guys! IMO that's worded very poorly - since they are saying additional cost, there's really no need to have that sentence.

Cheers!

Hmm...that seems simultaneously more complicated and less accurate than just calling diagonals in difficult terrain three squares. Or am I missing something?

When I read the title of this thread, I thought it was an advertisement for an even more litigious version of dungeons and dragons.

I am a little confused by the ruling on difficult terrain. By RAW, it seem like you travel and extra 2.5 feet worth of movement when moving diagonally though difficult terrain. This is a minor gripe I guess, but what it boils down to for me is that if I were traveling through a large area of difficult terrain I could go 100 feet in one direction, but if I went diagonally I would be able to travel 125 feet for the same movement cost...
Shouldn't each square of diagonal movement in difficult terrain cost 15 feet of movement?

And as long as we are on the topic of movement, wouldn't it be easier to say a square of movement if five feet, then measure movement in squares? Then instead of counting out movement by multiples of 5 (or 10 or 15) you could just count out squares... I see too many people miscounting by 5 for some reason so I admit this is a pet peeve of mine...

I just read Bugleyman's post, he is exactly right and is the same point I am making but in a much more concise way!

I just found out the distance traveled diagonally is 7.04 feet not 7.5 (I swear I read somewhere it was 7.5 feet.. 3.0 or 3.5 maybe?). That being said, I would rather use the Raw rules and give a little leeway to the player as far as movement. I really thought it was exactly 7.5 feet and was making my statement from that false pretense!

Say you wanted to move 4 squares. Moving diagonal normally costs 5 10 5 10 feet of movement, rather than the 5 5 5 5 feet of movement of a normal, non-diagonal Stride.

Difficult terrain adds 5 feet of movement, so Striding diagonally in difficult terrain would cost 10 15 10 15 feet of movement. (As opposed to the 10 10 10 10 feet of movement for a normal, non-diagonal Stride through difficult terrain.)

The odd phrasing was likely done the way it was to prevent confusion with people coming from 1st Edition rules, which worked differently by doubling all movement costs, not by being additive. In 1st edition moving diagonally through difficult terrain would have cost 10 20 10 20 feet of movement (5 10 5 10 doubled).

Hope that helps.
