Set Bonus is a special temporary buff applied to your character depending on the items you are wearing. It is calculated from 7 item slots: Helm, Armor, Pants, Boots, Gloves, Weapon and Shield.
The biggest impact comes from the number of Excellent options on your items. Item grade (e.g. Pad is low, Hades is high), item level and the Luck option are also taken into account.
What Set Bonus affects
Set Bonus increases the following attributes: Physical Damage, Wizardry Damage, Critical Damage and Maximum Life.
Maximum values are not capped. For example, with a Set Bonus of 500 you get +15% Damage & Defense, 4500 HP and 375 additional Critical Damage. This can be reached with a Great Dragon set +12 + Luck + 3 Excellent options on each item.
In short, every item, every level and every option adds to the overall power of your character. Your current Set Bonus is shown in the buffs panel and updates instantly when you change items:

Full armor set bonus
If you wear a full set of matching armor (helm, armor, pants, gloves and boots, all from the same set), the server grants you defense bonuses.
Requirements
- All 5 pieces must belong to the same set.
- If even one item is from a different set, broken or missing, the bonus does not apply.
What you get
- +10% Defense Success Rate simply for wearing a full set, regardless of its refinement level. This is a 10% increase of your current value, not a flat +10%.
- Defense bonus that depends on the refinement level (see the table below).
| Refinement of all pieces | Defense bonus |
|---|---|
| +15 | +30% |
| +14 | +25% |
| +13 | +20% |
| +12 | +15% |
| +11 | +10% |
| +10 | +5% |
Important: the bonus is calculated from the weakest piece. The bonus is determined by the lowest-level item in the set. For example, if 4 pieces are +13 and one is only +11, the whole set counts as +11 and you get only +10% instead of +20%. So upgrade the whole set evenly: one lagging piece drags the entire bonus down.
