The attribute Permanent is only relevant if you plan to Reincarnate. After reincarnation, regular items and sworn swords are lost, while any item marked as Permanent will stay in your storage and you can keep it after reincarnation. There are several types of permanent items.
Talents
Each time you reincarnate, you will be asked to choose 1 Talent, which will be made permanent for you. Most players choose to make those talents permanent which enable construction of fealty buildings. Such fealty building talents only have 1 point and are available at level 13.
If you choose to make a permanent talent (other than fealty building talent) from the fealty section, you will only unlock 1 point from that talent, while the rest of them will be locked until you choose that specific fealty again. To unlock that talent's full potential, you would need to reincarnate 8 times in the same fealty and unlock all 8 points of that same talent.
Sworn Swords
Some legendary and peerless sworn swords can only be purchaised with Gold (); they are permanent by default.
Other sworn swords, regardless of quality, can be made permanent by unlocking at least the first Seal slot, which requires Gold. First Seal slots cost 3 Gold, additional slots cost 2 Gold more than the previous slot.
While a permanent Sworn Sword will persist through reincarnation, all equipped items will be removed. If those items were permanent as well, they will be available for you after reincarnation, the rest of them will simply disappear. The same applies to items equipped on your character.
Companions and Units
Companion is a special type of unit which can generally only be purchaised from the shop with Gold; all companions are permanent by default, except in very rare cases of rewards such as the Goose.
To make a normal unit permanent, you need do one of the following:
- Rename it - cost 2 Gold
- Unlock first Seal slot (common units) - cost 3 Gold
- Unlock at least second Seal slot (uncommon or better units) - cost 5 Gold for second slot, 2 extra Gold for every next level
Weapons
To make a Weapon permanent you need do one of the following:
- Rename it (cost: 2 Gold)
- Unlock first Seal slot (common weapons) (cost: 3 Gold)
- Unlock at least the second Seal slot (uncommon or better weapons) (cost: 5 Gold for second slot, 2 extra Gold for every next level)
Armors
To make a piece of Armor permanent you need do one of the following:
- Rename it (cost: 2 Gold)
- Unlock first Seal slot (common Armors) (cost: 3 Gold)
- Unlock at least second Seal slot (uncommon or better Armors) (cost: 5 Gold for second slot, 2 extra Gold for every next level)
Seals
Seals by themselves cannot be made permanent.
However, If you apply a Seal on your character or on any item made permanent as described above, that Seal will persist through reincarnation.
