I just looted Madawc's statue (the one that we normally loot on mephisto TZ) on Andy (TZ).

I thought we could only loot Talic's statue on Andy TZ.

How is that even possible ?

I have only got +1 and -1 from them.
Meaning a Korlics from Andariel or a Worsuks from Diablo for example.
One time Mephisto also gave me a Korlics.
But i never got a +-2

I've gotten bk, talic and worusk from Andy, so no idea why people keep claiming certain bosses only drop certain statues. Seems random to me.

I’ve seen folks claim the act statues have a higher chance to drop from their respective bosses but they aren’t strictly bound to a single boss. Which makes sense. If you never happen to be online when a certain act boss is terrorized you’d be screwed.
