NOTES:
Daddy Longlegs switched places with Cactaur Jack in a recent update.
The NMs that drop Flametongue and Frostbite have been swapped.
Links have been provided to ZAM's Item and Mob Databases where possible.

does anyone know the drop rate on how often these items drop ?

and mayber the respawn times just curious

pretty sure catuar jack is 5 mins on respawn that is the only one i have famed so far

Please note that for the following paragraphs, I had to place extra spaces when I talked about time. I originally posted the info without the spaces and received some odd smilies.

Barring a recent change I am unaware of, the spawning time is actually divisible of 5 in the minute slot. By which I mean, it doesn't matter when you kill the NM (at least the ones above) once the clock hits x : x 0 or x : x 5, then they will respawn.

For example, if I killed the Unknown Soldier (which may not be the best choice of words since he is already dead) between 8 : 0 0 to 8 : 0 4, he should spawn at 8 : 0 5. If I kill him from 8 : 0 5 to 8 : 0 9, he should spawn at 8 : 1 0.

I haven't seen any solid data as it relates to drop %, but from personal experience, it wasn't too bad. For most of the above that I killed while farming for their drops, I would estimate I would get it from 1 to 5~6 kills, and quite a few were obtained on the first drop (though it was still less than half). However, a big exception to that would be Spitfire. I lost track of how many times I killed that little Spriggan, but I was never able to obtain the drop. I eventually gave up and leveled my CNJ without the staff; and if I remember correctly, I leveled my GLA after giving up on him for a second time trying to get the boots (at least I think that was the class I was trying to get the boots for).

thanks kat i appreciate it that explains why im getting variations in the spawn times ^^ as for the percentage its not that bad as i have gotten most of the items i was farming relativly quickly thanks again ^^
