Well, if you want an exact time-scale... no idea.^^ I played the game not that excessive, just a run (most of them in the inner quarters) here and there, all in all it dont feel i need that much time, i got the last one on may 28, 13 days after the release, and i perform a second start... so less than 2 weeks, each day an hour or less... not that much...
It all depends on how efficiently you do it. If you have grab maxed out and trained up, you go to the outer areas and just make an army of trolls to fight for you while you run around and focus on leveling specific weapons by using them exclusively. Another way to level weapons fast is to use traps, which hold enemies in place so you can do what you want to them.
I keep playing the first quest to conquer the South Outside, and I have killed 150 undead well withing the given time, many times over... but it never lets me take control. The dagger is always there, I cannot get any new missions
Wow that was a fast reply, thanks I was about to say that the Orc Ologs aren't called trolls so that might be why, but apparently not.
The battlefield fights seem like a bad place to try and get 10 all captured and alive at the same time because of the stupid amount of other enemies, but I've never seen a normal mission with 10 in it before I don't think
I got so caught up catching trolls I somehow cut my gum whilst eating a hard crust of bread, so I was bleeding all over the place trying to hold my mouth shut to keep it in whilst in game :P Dedication!
@Rich666 To have 10+ trolls in one game you have to have 100% danger in zone (I think).
My strategy was to capture them with trap so they couldn´t follow me, get rid of the other zombies and when the only trolls are left use the shot which turns them on your side.
100% is not needed, i got them at somewhat about 60% (last quarter).
First i walked around, kill the others with bow/crossbow from the idstance, then lay traps and attact a troll/olog and lure him into a trap... then i repeat, after a while i catch the trapped ones.
