Question about socketing Larzuk

I recently found

Eth

Diamond Mail. Being elite, it might make for a decent base for a runeword. However, how many sockets will

Larzuk add to it? Does he always add the maximum number of sockets possible, and so therefore it would be four? I can't find the rule on this. Thank you.

Larzuk will give it 4 sockets, and it's always the maximum as per item level. The only time he'll give less is if you upgraded a low quality version.

Perfect, ty.
