Larzuk's Puzzlebox is a new item in PD2 with a droprate that is similar to a high rune. Note that the ethereal armor bug has been fixed in PD2. 'Standard' refers to items that are neither Superior nor Inferior.
The maximum sockets an item can get is always restricted by the item base. Sockets can only be added to 0-socket items that are capable of gaining sockets: helms, chests, shields, and non-throwing weapons. These recipes no longer require any gems. The rune-upgrading recipes now require a key in addition to the runes. The gem-upgrading recipes are the same except the recipe for upgrading Flawless Gems, which now requires a key in addition to the gems. Some other items are newly stackable as well, and those items can be stacked/unstacked in the same way.ġ unstacked Gem/Rune + remaining Stacked Gems/Runes
They can be switched between their stacked and unstacked forms by cubing them.
Flawless Gems, Perfect Gems, and all Runes are now stackable.
