really general question about Sneak Attack

[washout]

What are the prerequisites for dead eye shot and how does it work exactly? You can just sneak attack anyone within 30 feet that is engaging someone else?

 

[StreamOfTheSky]

It requires BAB +4, PBS, Precise Shot, and sneak attack or skirmish. Feat lets you choose an enemy to ready a ranged attack against if it is struck by an ally in melee. When/if that occurs, you catch the foe flatfooted. So, a decent way for a ranged rogue to guarantee one SA/round. Of course, all that readying means lots of delayed turns, so over the course of several uses you may also effectively lose a turn

 

[Hypersmurf]

Your rogue can take adaptable flanker (PHB2) and wield a spiked chain to flank by himself (by standing adjacent to a foe and designating the opposite square).

Flanking by yourself is not an option; the text in the PHB refers to drawing a line between two characters, and the glossary describes flanking as being on the other side of a character being threatened by another character. Drawing a line between one character in two places won't meet the requirements.

More on mobility

This is a bit of a tangent, but a great way to improve your mobility is to take a level of sorcerer (if you have a reasonable charisma (at least 11)) and use expeditious retreat liberally. You can REALLY motor around the battlefield with an extra 30' of movement per round; my halfling rogue would never have any fun at all without it.

The main problem of using Expeditious Retreat is casting time. You often does not have time to spend a round for this spell. So, Swift Expeditious Retreat (Spell Compendium) is another good option. You can use this spell by taking either a level of Sorcerer or Duskblade (PHB II). I prefer Duskblade for this purpose as you can ignore light armor for spellcasting and can have better BAB, Saves & hit points.

Taking a level of cleric with Celerity domain (see Complete Divine or Spell Compendium) is another good option. This domain gives you unnamed bonus of +10 to your land speed (always active) and also give you expeditious retreat as a domain spell. As this is an unnamed bonus, it stacks with any other speed bonuses from items, spells & class features.
