Move Silently (DEX; Armor check penalty)

(Player's Handbook v.3.5 variant, p. 78)

Description

You can use this skill to sneak up behind an enemy or to slink away without being noticed.

Check

Your Move Silently check is opposed by the Listen check of anyone who might hear you. You can move up to one-half your normal speed at no penalty. When moving at a speed greater than one-half but less than your full speed, you take a ?5 penalty. It's practically impossible (?20 penalty) to move silently while running or charging.

Noisy surfaces, such as bogs or undergrowth, are tough to move silently across. When you try to sneak across such a surface, you take a penalty on your Move Silently check as indicated below.

Action

None. A Move Silently check is included in your move-ment or other activity, so it is part of another action.

Special

The master of a cat familiar (see the Familiars sidebar, page 52) gains a +3 bonus on Move Silently checks.

A halfling has a +2 racial bonus on Move Silently checks because halflings are nimble.

If you have the Stealthy feat, you get a +2 bonus on Move Silently checks.
