Each item can have slots - the amount is dependent upon the level of Path of exile currency the item as well as its type. There are two more attributes of these nests here. To begin with, they are able to have 4 distinct colors. Green, blue and red, in which where you are able to place any stone you may place skill stones of the colours, or white.

The second thing is the connections between the sockets. The sockets can be free, but they can also be connected by means of chains with each other. The second solution is much more desirable since it allows you to combine skill stones together with support stones - the former gain bonuses. Appropriate choice of abilities and their combinations is one of the most crucial things in Path of Exile.

All skill stones and support stones that have been placed in the character's stock will continue to grow as more creatures are murdered. Thanks to this it's likely to elevate their levels without the need to directly use abilities - they need is to be available.
