How can you get the cold head for the flail of ages? Options

[Kal]

Using IA V4.2 I played through the game without ever finding the cold head or therefore being able to finish making the flail of ages, I went through the De'arnise keep multiple times, making sure to kill everything inside and out, and searching every container.

The cold head was of course not in the lion head statue as that's been removed... "New location and Guardian for Flail Head (cold)" so where is it supposed to be exactly? Looking through these forums there were only two posts that mentioned it: Saying that a Greater Yuanti dropped it, I can't entirely remember if I killed this creature, but I believe so, on the off chance that I didn't do so where is *it* supposed to be located exactly, as well.

I even searched the bridge district after seeing Sikret say on one post "The forged flail should not disappear if you have killed Greater Yuanti, the whisper Spider (at bridge) and Glaicas." in case he wasn't talking about the spider near the drawbridge on the keep lands

Welcome to BWL, Kal!

The flail head (cold) is either with the Greater Yuanti or with the Whisper Spider. When you open the bridge of D'Arnise keep, both of these creatures will spawn and will be available.
