Archery questions

[leezard]

Ok so I was duoing with my brothers cleric last night in Oasis, on my warrior,
yes i know this is not warrior section but its a general melee/ranger thing I'm wondering

I was pulling with my Runed Oak Bow, using self fletched arrows (med nock, wood shaft, field point tips, large fletchings) and two things happened..

First, I was able to score damage on Crypt Mummies and Ghouls on my pulls..
Now I must admit it has been some time now since I had a low level char without magic weapons, BUT I'm pretty certain that they require magic weps to hit? If this is the case.... I was fairly certain the arrows must be magic also...

Second, as a wounded deepwater wandered off while I was dodging a Sand Giant, I managed to get a shot off and got a Crippling Blow with my bow.. and from what I remember rangers were the only ones to get bow crits?\

I did some searches and perused the bug forums but didn't come up w/ much, I was wondering.... Is this correct? Do I just remember incorrectly? Or should I submit a bug report... I'm loathe to do so until I feel certain it is warranted. Thank you for your time....
