# Thread: Speed of sound with a white dragon

1. ## Speed of sound with a white dragon

I was just randomly thinking of how to break the speed of sound somewhat simply and thought of this:

A colossal+ paragon white dragon wearing a belt of battle with the run feat and having the spell iron body cast by itself on itself.

It has a movement speed of 350 (700 but half from iron body). While running this becomes 1750. Straight down it's 3500. Taking an extra full round action means it moved 7000 feet in a round.

6 seconds in a round means 7000/6 = 1166.7 feet per second. Speed of sound at sea level is 1,116.43701 foot per second. Between down and up of clumsy maneuverability is 20 feet. So the dragon can avoid splatting against the ground and thanks to iron body it shouldn't suffer any of the G-Forces involved.

This is a really horribly evil way to initiate a fight against Pcs.

No one's going to survive something colossal moving 7000 feet down in one round, especially when its technically a colossal hunk of iron, essentially. Not to mention the crater it'd make.

If the party wizard can't survive a supersonic dragon made of iron at epic levels it's his own fault really.

Good Point. Seems like featherfall would be good enough to fix its initiation?

Sounds really awesome.

Contingency Teleport. :D

You have to wonder how paranoid your PCs are when "If a white dragon tries to divebomb me at supersonic speeds" becomes a specification for activating a Crafted Contingent Spell. Then you have to go home and rethink your life.

Far more reasonable is "if anything threatens me."

9. ## Re: Speed of sound with a white dragon

I always liked that Dragon Magazine spell for dragons to fly in a straight line at 4 times normal speed. Think it had something to do with arrows.

10. ## Re: Speed of sound with a white dragon

I could have sworn there was a flaw or feat, or spell, or something that changes your mass. I would suggest taking that as well, so now he comes hurtling down like a lead dragon, rather than an iron one. Now that is an impact zone.

...And your wizard becomes the favorite toy of small children everywhere, as word spreads that yelling 'gonna throw mud pies at you, Wizard!' causes him to become fenced in by a glowing, impenetrable array of warding spells and/or teleported back to his dimensionally-locked private plane.

I did mean threaten in the game mechanics sense, but that may or may not be valid for contingency; the spell is hideously vague that way.

Thrown anything doesn't threaten (ranged attacks), mud pies wouldn't threaten (not a weapon), etc.

Well now we're talking about metaphysical gaming constructs. Your wizard doesn't know what those are~!

Debatable, particularly in the case of AoOs where characters are basing their decisions based around the mechanical realities.

Yeah if played intelligently most high level monster encounters should start and end that way.
>:D

It's sort of like how a genius in our world probably knows a fair deal of math and science. By sorting through natural phenomena, a wizard school could get a fairly good idea of how such meta constructs work.

A PC Wizard is going to be rocking a 30+ Int score, max ranks in several Knowledge skills, and the ability to text message Gods on a whim. He knows. My sig happens to be relevant here.

18. ## Re: Speed of sound with a white dragon

Similarly, I had a character that Shapechanged into a Very Young Polychromatic Dragon with a 720ft/round fly speed. With the Run feat and his speed boosts factored in, I worked out that he could take Run actions at about the speed of a jet liner.

19. ## Re: Speed of sound with a white dragon

Forgive me for being ignorant, but how would 15/adamantine protect the dragon from hitting the ground at over 4,4 billion newtons?

I totally want to sig this. May I please?

21. ## Re: Speed of sound with a white dragon

Didn't Chuck (the Ruby Knight Windicator) make it up to six times the speed of sound, or something?

I'm very uncomfortable with this idea. Just because the rules are based on six second rounds, ability scores, etc. doesn't mean that it's necessarily an aspect of the physical reality of the game world. Personally, I wouldn't let this fly at my table.

23. ## Re: Speed of sound with a white dragon

Are you considering that Iron Body halfs your speed? Or you are assuming that it only affects land speed?

Don't get me wrong, I saw this idea and tried to apply it to my druid and saw the spell and figured that my usual DM would apply that penalty to all kinds of movement speed.

What is the terminal velocity of an iron dragon?

Approximately magic meters/second.

He did, and was ridiculous. But wasn't he broken by some errata or other?

IIRC, they wrote an errata to explicitly prevent Chuck... and miswrote it so that it still works. Or something silly like that.

If you're referring to the original build, I'm pretty sure the Complete Arcane errata totally destroyed the Footsteps of the Divine trick by disallowing Persisting dischargeable spells. If not, I'd like to hear this new speed record guy.

I don't know how to determine the volume of a Colossal+ White Dragon, but if I could I'd probably be able to calculate his ferrous terminal velocity.

29. ## Re: Speed of sound with a white dragon

I could easily be misremembering.

Wait, Faerun or Forgotten Realms?
