Infusible ArmorFollow

There is a square on your inventor screen for a power source. The sources are globes of different types which when equiped adds and subtracts stats.
Sources start out as murky then upgrade to foggy and other names.
I have only seen murky for sale in the bazaar.

You need a powersource:

Each powersource adds different stats, the lower ones are crafted with tradeskills, and the good ones are bought in Katta Castrum once you have sufficient faction, and an alternate currency called Orum.

The purity stat on infusible armor and weapons is a percentage of how much of the powersource's stats you will get when you equip it. Both armor and weapons will get stats, and weapons will also get a proc.

The more infusible stuff you have the faster the powersource will drain. When it burns out, you have to get a new one.

This is a page detailing the stats that each powersource adds based on certain purity values:

Hope that helps!

Thanks very much for your answers its sort of helpful. I just checked my inventory screen and can find no square for a power source. Do I need all expansions for this to show up? Or am I doing something wrong?

Thanks very much Balayan.
