Natural Climber (3.5e Feat)
From D&D Wiki
Natural Climber [General]
You have achieved a skill at mountaineering that you could challenge a chamois.
Prerequisite: Climb 25 ranks
Benefit: You gain a natural climb speed, which is either half your normal land movement speed or your Climb skill ranks in ft., whichever is higher. You can climb at your full land speed or twice your skill ranks in ft. if you take a -5 penalty to your climb check. Note that speed is always rounded down to the next multiple of five.
Special: You gain the following advantages for having a natural climb speed: You can always choose to take 10 on Climb checks even if rushed or threatened while climbing. You retain your Dexterity bonus to Armor Class (if any) while climbing, and opponents get no special bonus on their attacks while you are climbing. This feat does not grant a bonus to your Climb skill.
