a Nightfall giant  

New location of the Nightfall Giants are:

-621.48, 43.24, -185.30

I don't know the coordinates but I specifically recall what area: If you know where the entrance to Lavastorm is(in the middle of the very north) then you go slightly southwest from there and wander the forest and you are guaranteed to find some of these. So basically they wander in the north western part of nektulos forest. Keep in mind that the fairies are nearby.

If you need giants in general then I recomend the ones in TS instead, much easier to find but if you need nightfall giants specifically such as for the quest that crazy troll that wanders in CL near NF gate gives then I suggest you invis when wandering the forest until you find one that isn't too close to the other aggressive monsters.

Wish I knew. They all have the plague it seems. Curse you Bertoxxilous.
