mm.. I thought all pala shields got 4os regardless of ilvl. Hell/nm/normal socketing is irrelevant, it's all the same. The item's ilvl is what determines the number of sockets. Larzuk will always give maximum sockets, determined by ilvl. In this case, it'd get 6os, unless it was cubed from a lowquality/cracked zerker.
If you want lower # of sockets, use the cube formula: ral + amn + perfect amethyst. It'll randomly socket it.
