Benefit: A rogue with this talent gains a +4 circumstance bonus on all Sleight of Hand checks made to conceal a weapon. Furthermore, if she makes a sneak attack during the surprise round using a concealed weapon that her opponent didn’t know about, she does not have to roll sneak attack damage, and the sneak attack deals maximum damage. A rogue can only use the underhanded talent a number of times per day equal to her Charisma modifier (minimum 0).
This is a rogue talent that I could take on any even numbered level with a rogue.
Question: If I'm invisible, and I sneak up on a creature, does that count as a concealed weapon that the opponent didn't know about, or do I still have to make a slight of hand check to conceal the weapon? Question 2: When I use this, does it count for just the first sneak attack, or all attacks if I get mutliple attacks in the round? Situation: I'm invis and I sneak up on a creature. I wait a round to attack, thus getting all my attacks. BAM, do I get one max'd attack, or will all my attacks be max'd?
