What the plus level is
Besides its level and quality, an item can carry a bonus level, shown as a plus number: a +1 ring, a +6 helmet, a +12 blade. The official guides call it the bonus level. It goes from +1 to +12.

Do not mix it up with the item's level (raised with Meteors) or its quality (raised with Dragon Balls). Those are explained in Item quality and level.
Raising it by composing
- You raise the plus level by composing: the item you want to improve is the main item, and a +Stone or another + item of the same type is the minor item that is used up.
- Every +Stone or + item is worth a number of Composition Points. A +6 Stone or a +6 item of the same type, for example, is worth 3,240 points.
- A plain normal weapon or armour piece cannot be used as the minor item.
- A bound +Stone works only on gear that is also bound.
- Talismans are composed the same way, and a +1 Heaven Fan or +1 Star Tower can drop from monsters. See Talismans.

Why high plus is so valuable
Each plus step is worth much more than the last. The official talisman guide shows this well: when you feed an item into a talisman to open a socket, its plus level decides how much progress it gives.
| Plus level | Talisman socket progress |
|---|---|
| +1 | 6 |
| +3 | 80 |
| +5 | 740 |
| +6 | 2,220 |
| +8 | 20,000 |
| +9 | 60,000 |
| +12 | 72,000 |

Plus items and Perfection
On modern servers, +Stones and + items are also the fuel of the Perfection system, which tempers Super gear. Their Composition Points become Perfection Progress: for example, three +8 Stones take an Archer hat to the 9 Moons stage.
