Your body seems light as a feather, though your weight does not actually change. This power has no effect on your equipment. If you fall while this power is in effect, you suffer 1d6 point of damage for every 60 feet you fall; you take no damage from falls of less than 60 feet.
While this power is in effect, you gain a +8 bonus on Climb checks you make to climb any vertical surface (not a ceiling or negative slope), and you climb at half your normal speed (or your normal speed if you make an accelerated climb). You retain your Dexterity bonus to Armor Class (if any) while climbing, and opponents get no special bonus on their attacks against you.
Also while this power is in effect you gain a +8 bonus on Move Silently checks.
If you spend 4 additional power points, the duration becomes 1 hour.
