Arcane Trickster - Ranged Legerdemain

Can someone please make some sense of this for me?

Ranged Legerdemain: An arcane trickster can perform one of the following class skills at a range of 30 feet: Disable
Device, Open Lock, or Sleight of Hand. Working at a distance increases the normal skill check DC by 5, and an arcane
trickster cannot take 10 on this check. Any object to be manipulated must weigh 5 pounds or less.
An arcane trickster can use ranged legerdemain once per day initially, twice per day upon attaining 5th level, and three times
per day at 9th level or higher. He can make only one ranged legerdemain skill check each day, and only if he has at least 1
rank in the skill being used.

What is this about only making one ranged legerdemain skill check each day if you can use it twice per day at 5th level, three times, etc.

Hmm, each skill only once... Once Disable Device, once Open Lock, once...

Obviously, this is an error. Best guess is that they meant to limit the character to one skill check per use of the ability-eg., you can't declare a use of RL to open a lock, and then make multiple Open Lock skill rolls (or take 20). One skill check roll, then you're done, unless you have another RL daily use available.

You can ignore the part about only being able to do it once per day.

The AT can use any of those skills (even the same one multiple times) 1-3 times per day, depending on class level.

Has been clarified somewhere (FAQ?), but don't ask me where!

Bye
Thanee
