🪓Enchant grade system
1) Overview
Enchant Grades add a progression layer on top of refining. You keep refining your weapon like normal, then improve its grade to boost the value of those refines and, at Grade A, unlock extra per-refine perks.
Key points
Grades run D → C → B → A.
You can upgrade grade at the Enchant Grade Master (Haldier).
Your current grade is shown as [D] / [C] / [B] / [A] in menus/tooltips.
Only Grade A grants extra bonuses per refine (see Section 5).
2) How Enchant Grades Work
Each eligible item (mainly weapons) starts at Grade D.
You can rank it up to C, B, and A using materials and Zeny.
Grades affect:
Refine scaling (how much benefit you get from each refine level).
(Grade A only) Extra bonuses that scale with your item’s refine and weapon level.
If you see the grade tag like [A] next to the item name or in the UI, that item is already Grade A.
3) Rank Up Your Gear
Find Haldier (Enchant Grade Master) in the main town.
Choose the item you want to upgrade.
Confirm the material & Zeny cost (varies by grade step and item).
If the attempt succeeds, your item’s grade increases (D→C, C→B, or B→A).
4) Grade Bonuses at a Glance
Most of the magic happens at Grade A, which adds per-refine perks. For D/C/B, expect standard refine behavior (the exact multipliers are server-configured).
You always keep your normal refine benefits; Grade A just layers extra bonuses on top.
5) Grade A — Per-Refine Bonuses
At Grade A, your weapon gains extra bonuses that scale with refine level and weapon level.
"Per refine" means the bonus is multiplied by your current refine level. Example: If a perk says +3% per refine and your weapon is +10, that’s +30% total from this perk.
Weapon Level rules for Grade A
Weapon Level
Extra Critical per refine
Extra Damage vs all elements per refine
Attack speed per refine
WLv 1
+2 Crit
(no extra elemental damage)
(no extra aspd)
WLv 2
+3 Crit
+1% (physical and magical)
(no extra aspd)
WLv 3
+5 Crit
+2% (physical and magical)
+1% (aspd)
WLv 4
+8 Crit
+3% (physical and magical)
+2% (aspd)
“Crit” here is the value you see on the character window.
"Damage vs all elements" applies against Neutral, Water, Earth, Wind, Fire, Holy, Dark, Ghost, Poison, and Undead targets, for both physical and magical damage.
Quick examples
WLv 4 Grade A +10 → +80 Crit and +30% damage vs all elements from Grade A perks.
WLv 2 Grade A +12 → +36 Crit and +12% damage vs all elements from Grade A perks.
WLv 1 Grade A +9 → +18 Crit (no elemental bonus).
These bonuses are in addition to any other refine effects, cards, enchants, or skills.
Refine Grades - How the Bonus ATK Works
The Grade on your weapon multiplies the ATK you get from refine. For Weapon Level 1 (WLv1), base refine gives +2 ATK per +1. Grades add extra % on top of that base:
Grade D = +50% more refine ATK
Grade C = +150% more refine ATK
Grade B = +250% more refine ATK
Grade A = +350% more refine ATK
1) The Base: Refine ATK (WLv1)
By default on this server, WLv1 weapons gain +2 ATK per refine.
Examples with no grade:
+1 → 2 ATK
+5 → 2 × 5 = 10 ATK
+10 → 2 × 10 = 20 ATK
This “base refine ATK” is what the Grade multiplies.
- 2) The Grade Bonus (WLv1)
Grades add extra % of the base refine ATK. Formula (showing the extra and the total):
Grade D (+50%)
+1: 2 + 50% = 3 ATK (2 + 1)
+10: (2 × 10) + 50% = 20 + 10 = 30 ATK
Grade C (+150%)
+1: 2 + 150% = 5 ATK (2 + 3)
+10: 20 + 150% = 20 + 30 = 50 ATK
Grade B (+250%)
+1: 2 + 250% = 7 ATK (2 + 5)
+10: 20 + 250% = 20 + 50 = 70 ATK
Grade A (+350%)
+1: 2 + 350% = 9 ATK (2 + 7)
+10: 20 + 350% = 20 + 70 = 90 ATK
Tip: The % is applied to the base refine ATK, not to your total ATK stat. In practice, the server calculates with integers (fractional results are truncated).
