How many slots would be made in larzuk?

I am going to take a tiny chance here and say 5 sockets 100% of the time. Since it is an elite base, most likely only found in late nightmare and through hell, which are all above level 41 area level places. So it will always get max sockets.

Cubing is a different story. 1/5 chance to get 1-5 sockets, since 5 is the max sockets that item can get.

5 sox

damn its 14/15 eth :<

What's the problem with that? You can larzuk socket superior + eth items?

yeah but i thought that would be 4soc

Ah yes, that's a gamble with the cube. But remember some 4 socket runewords only work with polearms, not spears.
