Blindsight, Blindness and Silence

[Nathan]

Next session our gaming group will probably have to deal with a black dragon (of large size).

I have two simple questions:

1) Can the spell blindness/deafness negate a dragon's blindsight ability?

2) Is silence together with invisibility enough to foil the dragon's vision?

If you use stink bombs and a cloud of bees (to fool the moving air sense aspect) it may work.

Aggemam is correct on both counts.

Blindness obviously does not negate blindsight, and deafness would only work if the dragon's blindsight depended solely on hearing, which it does not, according to the MM. Also, remember that dragons have been errata'd to have the Scent ability at 30 feet per age category.

Well..

According to Dragon Magazine 296 (I believe it was) a dragon's blindsight can be fooled by silence. It is still capable of 4xLow Light Vision, Darkvision, and Scent, though.

If somehow blinded (negating low-light vision and darkvision), or fooled by a by a creature that is invisible and scentless (perhaps through pass without trace or Gwaeron's boots from MiF) using a personal silence spell, the dragon is actually as blind as anything else.

It still has the potential to guess and strike with 50% miss chance at such a foe.

Then the people who wrote the article is not sufficiently familiar with the rules to do so. The MM clearly states that the blindsight ability of a dragon does not depend on hearing, so they made an error (again).
