Attack Speed and Haste in MU Online: How to Calculate
Learn how attack speed works in MU Online S6, how AGI influences Haste, and the cap values per class with detailed comparison tables.
What is Attack Speed in MU Online S6
In MU Online Season 6, attack speed (displayed as Haste in the Status window) determines how many hits per second your character delivers. It affects both normal attacks and the casting cadence of most active skills. Understanding how to calculate and optimize it is essential for any competitive build.
Attack speed is shown in the Status window (press C) as a numeric value. The cap in S6 is 500 for all classes — any source that would push the value beyond 500 is wasted.
The Base Attack Speed Formula
The general formula used by S6 servers is:
Attack Speed = Total_AGI / Class_Divisor + Fixed_Bonuses
Where:
- Total_AGI = base AGI + distributed points + equipment bonuses + ancient set bonuses
- Class_Divisor = a constant that varies by class (see table below)
- Fixed_Bonuses = bonuses from wings, Fenrir, excellent options, and support skills
The result is truncated to an integer and capped at 500.
Divisors per Class and Effective AGI Cap
| Class | Divisor (S6) | AGI for cap (no bonuses) | Starting AGI |
|---|---|---|---|
| Dark Knight (BK/BM) | 3 | ~1500 | 28 |
| Dark Wizard (SM/GM) | 3 | ~1500 | 28 |
| Fairy Elf (ME/HE) | 3 | ~1500 | 28 |
| Magic Gladiator (DM) | 3 | ~1500 | 28 |
| Dark Lord (LE) | 3 | ~1500 | 30 |
| Summoner (BS/DiM) | 3 | ~1500 | 28 |
Equipment Bonuses to Attack Speed
Many items grant attack speed in addition to what AGI provides:
Weapons with Excellent Option
The excellent option "Increase Attack Speed +7" adds a flat 7 points of attack speed to the weapon. It is one of the most sought-after options for physical builds.
Wings
| Wing | Level | Speed Bonus |
|---|---|---|
| DK Wing (L1) | Level 1 | No fixed bonus |
| DK Wing (L2 — Dragon Wing) | Level 2 | +10 Attack |
| DK Wing (L3 — Cape of Lord) | Level 3 | +15 Attack |
| DW Wing (L2 — Wing of Eternal) | Level 2 | +10 Magic |
| Elf Wing (L2 — Wing of Illusion) | Level 2 | +10 Attack |
| Elf Wing (L3 — Wing of Mystery) | Level 3 | +15 Attack |
| MG Wing (L2 — Wing of Ruin) | Level 2 | +10 |
| DL Cape (L2 — Cape of Emperor) | Level 2 | +10 |
| Summoner Wing (L2 — Wing of Despair) | Level 2 | +10 |
| Any L3 Wing | Level 3 | +15 Attack |
Fenrir
The Fenrir pet grants a fixed +10 attack speed when equipped, regardless of its upgrade tier. This bonus is always active.
Ancient Sets
Certain ancient sets grant attack speed bonuses via 2-piece or full-set options:
| Set | Class | Speed Bonus |
|---|---|---|
| Hyon (Dragon Set) | Dark Knight | +10 (2-piece) |
| Gywen (Bow Elf Set) | Fairy Elf | +10 (2-piece) |
| Aruan (Thunder Hawk) | Dark Knight | +7 (2-piece) |
| Chrono (Divine) | Magic Gladiator | +10 (2-piece) |
Skills That Affect Attack Speed
Greater Haste (Fairy Elf / Muse Elf / High Elf)
Greater Haste is the most important attack speed buff in S6:
Haste (levels 1–10):
Base bonus: +20 Attack Speed
Bonus per skill level: +2 per level
Maximum (Haste level 10): +40 Attack Speed
Duration: 60 seconds
Mana cost: 20 (base)
Attack Speed Aura (Dark Lord / Lord Emperor)
The Dark Lord has a passive aura that increases nearby allies' attack speed by up to +15, scaling with the CMD (Command) stat — the attribute exclusive to the Dark Lord class.
DL Attack Speed Aura:
Base: +5 attack speed
Scaling: +1 for every 50 CMD above 100
Aura cap: +15
Attack Speed Comparison by Build
| Build | Target Total AGI | Speed (no buffs) | With Elf Haste (+40) | With Fenrir (+10) | Estimated Total |
|---|---|---|---|---|---|
| BK Full Strength | 400 | ~133 + item bonuses | ~173 | ~183 | ~183–220 |
| BK Balanced | 800 | ~266 + item bonuses | ~306 | ~316 | ~316–360 |
| BK Speed-Focused | 1200 | ~400 + item bonuses | ~440 | ~450 | ~450–490 |
| BK Capped | 1500+ | 500 (cap) | 500 | 500 | 500 |
| High Elf | 1000 | ~333 + item bonuses | — | ~343 | ~343–380 |
| Duel Master (MG) | 900 | ~300 + item bonuses | ~340 | ~350 | ~350–400 |
Step-by-Step: Calculating Your Attack Speed
Step 1 → Add up all your AGI:
Total_AGI = base_AGI + distributed_points + equipment_AGI_bonus
Step 2 → Divide by the class divisor:
AGI_speed = Total_AGI / 3
Step 3 → Add fixed bonuses:
total_speed = AGI_speed
+ wing_bonus
+ fenrir_bonus (if equipped: +10)
+ excellent_bonus (if active: +7 per weapon)
+ ancient_set_bonus (if active)
+ Elf_Haste (if in party or self-buff: +20 to +40)
+ DL_aura (if nearby: +5 to +15)
Step 4 → Apply the cap:
final_speed = MIN(total_speed, 500)
Practical Example: Blade Master
Assume a Blade Master with:
- 900 total AGI (base + distributed + equipment)
- L3 Wings (+15)
- Fenrir equipped (+10)
- 1 weapon with Excellent Attack Speed option (+7)
- Haste level 8 from an allied High Elf (+36)
AGI_speed = 900 / 3 = 300
fixed_bonuses = 15 + 10 + 7 + 36 = 68
total_speed = 300 + 68 = 368
final result = 368 (below the 500 cap)
To reach the cap of 500, this character would need an additional 132 points from more AGI or other bonuses.
