I am a newbie in this game, my character was already join fighter-marauder class, and know my char in the deathlord quest. I'm interesting with HAWKEYE diabolic skill, It is true that with HAWKEYE we can kill enemy with just single bow shot ?. If its true, I will try to join rogue-hunter-rangerlord. I love this game...
You can only have one third tier class per character. Since you're on the deathlord quest, that's going to be your third tier class, and you won't be able to become a ranger lord.
The good news is, ranged weapons tend to be so wimpy in the game that most people probably don't bother becoming a ranger lord. (I also have a vague recollection that critical strike and hawkeye are broken, but I've never played any of the classes with the skills.)

I am going thru the game for the second time. I completed the Ranger Lord promotion. Before I entered the Tomb of Souls I had reached the 10th level of Hawkeye and have the Necrotic Battle Bow 4-9. I am going thru the Shadow Ruins now and have just completed the Wind jumping area where you can sit back and at leisure shoot the Athena Bashers. Just before entering the Wind jumping area I put the necessary 3215360 adv points to climb to Hawkeye level 11. Even so at no time have I dealt a killing blow with my bow. I wear down an opponent with anywhere between 4 and 9 attack points just like every other battle you face. If at level 11 Hawkeye you can't deliver one killing blow my suggestion is to skip the Ranger Lord promotion as I see no value to it. By the way I am not bashing the game. I know even playing version 1.3 there are a few bugs in the game but all in all I have enjoyed the game very much and intend to go thru it again as another character. I was just disappointed that this feature did not see to work or is unclear in how to activate the killing blow.
