Seal & Circle is a system which creates sockets into an item for Seal(s) to be inserted in. By putting Seals into the sockets of an item, it becomes more powerful in battle. Seals have a duration of 60 minutes, and can be used until the item is destroyed.
CIRCLE
Various armors and weapons can be upgraded with Sockets which will allow Seals to be inserted for bonus stats. Certain items can be upgraded to have more Sockets than others.
To add sockets to an item, speak to the Seal & Circle Master, Holet in Caeldome and click on "Crafting Circle" (Must have a profession before using Seal & Circle).
Place the item you want to add a socket into the white outlined box in the window. You will need to supply Sealing Holes to create sockets. In order to craft items that contain sockets, the item must be at least level 20 (Feoh), and the sockets of each item are different.
There is a chance that this process may fail, and the weapon will be destroyed, but the runestones will come back.
A new socket will appear at the bottom of the item info if it was successful.
SEAL
Now that you've added sockets to the items of your choice, it is time to create some Seals to place into the sockets. Seals are consumable items. There are many kinds of Seals that can be crafted. * Seals are only valid in certain items (e.g. Melee Attack Power can only be attached on weapons).
Speak to the Seal & Circle Master in town and click on "Crafting Seal".
SEAL & CIRCLE
Now that you have Seals to be placed into the sockets of your item, press "V" to open the Seal & Circle window. The window shows all the sockets on each socketed item that is equipped.
While the socketed item is equipped on your character, you will see its associated icon type lit up. For example, if you created sockets for a bow and equipped it, then the Sword and Shield icon will be lit up (not greyed out). Drag the Seals you've created into the sockets for that item.
Once it is equipped, on the bottom left corner of the window will appear a play button. The button can be dragged into the Hot Key Window. As it's shown above (Screenshot), each created socket can be equipped, and all can be activated by pressing the "All" button.
Seals that are equipped in the sockets can be checked by pressing "C".
Using the UI button that was dragged onto the Hot Key Window will show the effect of the item.
As it shows on the Screenshot below, little blue spheres will float around the weapon (shields don't show any effect).
Seals have a timer shown above them, which lasts for an hour until the effect goes away. Right-click on the lit icon to activate the effect and click it again to pause it. For convenience, you can drag this icon from the Seal & Circle window to your Quick Slots.
Once the Seal runs out of time, you can insert another Seal into the socket again. Note: you cannot stack two of the same Seals into an item that has the same level.
