Lightfoot

Thievery is a discipline that calls to many, for many reasons.  Some become masters of locks and traps, others of poisons or thuggery, and still more of acrobatics or trickery or guile.  The lightfoot, however, is the master of stealth.  He moves as a part of the shadows, with grace and silence, never seen unless he desires to be.

Sneak Attack: Your Sneak Attack damage only increases every 4 levels, instead of every 2.

Stealth Bonus: At 1st level, you gain a bonus to Stealth checks equal to half your lightfoot level (minimum +1).  This ability replaces the lost Sneak Attack damage dice.

Fast Stealth: You must take Fast Stealth as your Rogue Talent at 2nd level.

Solid Shroud: At 2nd level, a lightfoot ignores the armor check penalty to Stealth checks from light armor.  This ability replaces Evasion.

Uncanny Stealth: At 4th level, you can make a Stealth check even when running or charging, though you do so at a -10 penalty.  You still cannot use Stealth while attacking (including the attack made at the end of a charge).  This ability replaces Uncanny Dodge.

Improved Uncanny Stealth: At 8th level, you no longer take penalties to your Stealth check when running or charging.  Additionally, you can make a Stealth check while attacking, though you do so at a -10 penalty.  You can also snipe from concealment with only a -10 penalty to your Stealth check.  This ability replaces Improved Uncanny Dodge.

Hide in Plain Sight: At 12th level, you can use the Stealth skill even while being observed.  As long as you are within 10 feet of some sort of shadow or cover, you can hide yourself from view in the open without having anything to actually hide behind.  You cannot, however, hide in your own shadow.  This ability replaces the Rogue Talent at 12th level.

Phantom: At 20th level, you are always considered to be taking 10 on Stealth.  It always requires a Perception check to detect you, unless you are actively trying to be seen or heard.  Additionally, you no longer suffer a penalty to your Stealth when attacking or sniping.  This ability replaces Master Strike.
