Best way to use Blindsight?

[CupcakeNautilus]

If a character manages to get Blindsight out to 30ft (such as with Blinded Master), what would be the best ways to take advantage of that?

Fog/Smoke or Deeper Darkness would do the trick, but likely hinder your teammates more than they're worth, I'd think.

There's other ways to see through fog. Magic items like Fogcutting Lenses or a Goz Mask for a start; if your team's working with you it should be doable. At 15th level the cost is not major.

If you've somehow got blindsight a lot earlier than Blinded Master will allow there's more of a problem. Careful placement of fog clouds/darkness might help. Otherwise you have a nice anti-invisibility ability.

Mistmail would be useful for creating a localized fog effect.

I'm sure there's higher level gear that functions even better along these lines.

Blinded Blade Style serves as the 10 Ranks of Perception Prerequisite for Improved Blind Fighting. So then when you have Concealment, you should still be able to Sneak Attack.

Moonlight Stalder Feats give you bonuses when you have Concealment. Moonlight Stalker Feint in particular lets you Feint as a Swift Action.

The Sniper's Eye Rogue Talent lets you ignore Concealment for the purposes of Sneak Attack Ranged Attacks.
