In my last game, I found myself in a couple of tight spots and tried to do a few 'tricky' things. My DM didn't allow them in the end, but I just want to know for future reference if I can actually pull these things off, or if my literal interpretation of these rules was just wishful thinking 
1) Is the Hail of Arrows ability a full round action? The description says:
"Hail of Arrows: In lieu of her regular attacks..."
Now, does this mean I have the ability to move as well as use this ability, in the same round? I actually had an extra partial action from haste, so I was trying to move (out of danger) then fire.
2) Do you have to physically see your target when firing a Seeker Arrow? The description says:
"Seeker Arrow: At 4th level, the arcane archer can launch an arrow once per day at a target known to her within range..."
Now, to me, this says I don't have to see them, I just have to know that my target is in range. I was actually blinded by some spell, and tried to use a seeker arrow. I thought I would be able to just fire it, say, straight up and it would find the target for me.
