MU Online Ability Cards Guide – Skill, Option & Elite Cards

Ability Cards are the endgame card system introduced with the Season 19 Ability Enhancement Tree (5th skill tree). Each character equips cards from a class-specific Ability Card Book: Skill cards unlock enhanced versions of your core skills, Option cards stack raw stats, and Elite cards add chance-based effects like Triple Damage. Combined with Lv. 5 wings and earrings, cards are where late-game character power comes from on Season 19+ servers.

The Three Card Types

	Card type	What it does	Slots
	[Skill] Ability Card	Unlocks an enhanced sub-skill of your class skill (wider area, more attack speed or splash damage) plus one random HP/MP/AG option	Skill slot
	[Option] Ability Card	Flat stat options (ATK, skillpower, DEF, elemental stats) — five Types, each fitting only slots of its color and type	Colored option slots 1–5
	[Elite] Ability Card	Chance-based premium options: Triple Damage, Ignore Defense, Excellent/Critical chance, full HP/MP recovery	Elite slot per color

All cards upgrade to a maximum of level 5. Colors (Blue / Green / Purple) matter: a card only fits slots of its own color, so building your board means collecting the right color-type combinations.

[Skill] Ability Cards by Class

Each class crafts its own Skill cards — an enhanced version of a signature skill with one of three effect themes: of Fire (bigger area of effect), of Gale (attack speed) or of Fury (splash damage). Examples from the official set:

Class	Skill card	Enhanced effect
Dark Wizard	Meteor Storm of Gale	Increased attack speed
Dark Knight	Sword Blow of Fire / Strike of Destruction of Gale	Bigger AoE / attack speed
Fairy Elf	Raining Arrow of Fire / Holy Bolt of Gale	Bigger AoE / attack speed
Magic Gladiator	Chaos Blade of Fire / Havok Spear of Fury	Bigger AoE / splash damage
Dark Lord	Wind Soul of Fire	Bigger AoE
Summoner	Fire Beast of Fire / Death Scythe of Fury	Bigger AoE / splash damage
Rage Fighter	Dark Scythe of Fire / Spirit Hook of Fire	Bigger AoE
Grow Lancer	Oversting of Fire / Wild Breche of Gale	Bigger AoE / attack speed
Rune Mage	Lightning Storm of Gale	Increased attack speed
Slayer	Pierce Attack of Fire	Bigger AoE
Gun Crusher	Bursting Flare of Gale	Increased attack speed
White Wizard	Sphere Storm of Fire	Bigger AoE
Mage	Ultimate Force of Fire	Bigger AoE
Illusion Knight	Blade Storm of Fire	Bigger AoE

Skill card names vary slightly between servers (e.g. of Saturation instead of of Fire) but the effect themes are the same. Every Skill card also rolls one random option: HP, MP or AG increase.

[Option] Ability Cards – Types 1–5

When crafting an Option card you choose the Type (1–5), but the color is random. Each Type has its own option pool:

Type	Theme	Notable options
Type 1	Strength / Fire	STR, Fire ATK/DEF, Critical DMG, Double DMG, Min ATK/WIZ/Curse, Nuke/Bolt/Wide ATK
Type 2	Agility / Water	AGI, Water ATK/DEF, ATK success rate, Lv. 5 Wings ATK/WIZ/Curse, Skillpower slots, Nuke/Bolt/Wide crit chance
Type 3	Stamina / Earth	STA, Earth ATK/DEF, Pentagram ATK, Excellent DMG, ATK per 20 levels, Max ATK/WIZ/Curse, Skillpower
Type 4	Energy / Wind	ENE, Wind ATK/DEF, elemental DEF and success rates, Lv. 5 Wings DEF, Pentagram DEF, Shield DEF
Type 5	Darkness / DoT	Darkness ATK/DEF, Poison/Toxic/Bleeding DMG, Mastery ATK/WIZ/Curse, shock defense

[Elite] Ability Cards – Options by Color

Elite cards let you choose the color when crafting — and each color has its own premium pool:

Color	Option pool
Blue	Full HP Recover chance, Skillpower 1-Slot, Critical DMG chance, Double DMG chance, Nuke/Bolt/Wide Excellent chance, Extra DEF
Green	AG recovery, Skillpower 2-Slot, Excellent DMG chance, Ignore Enemy Defense chance, Nuke/Bolt/Wide Double DMG chance, Extra DEF
Purple	Full MP Recover chance, Skillpower 3-Slot, Additional DMG chance, Triple Damage chance, Nuke/Bolt/Wide Triple DMG chance, Extra DEF

The Elite craft can also return 5 Ability Upgrade Stones instead of a card — it is the only craft with a random outcome, so check your server's probability info before spending crystals.

Crafting Costs (Chaos Goblin, Noria 180 103)

All card crafts happen at the Chaos Goblin and all succeed at 100% — the gamble is in the random rolls, not the craft itself. The currency is the Ability Crystal, farmed from high-level hunting, bosses and events:

Craft	Ability Crystals	Jewels of Bless	Zen	Result
[Skill] card	50	10	100,000,000	Your class's Skill card
[Elite] card	25	5	50,000,000	Elite card of chosen color — or 5 Upgrade Stones
[Option] card	5	1	10,000,000	Option card of chosen Type, random color

Level-Up and Salvaging

Right-click any obtained card to open the Ability Level-Up / Salvage window. Leveling a card to its maximum of level 5 consumes duplicate copies of the same card plus Ability Upgrade Stones — the exact amounts are shown in the UI per level.

Duplicates you do not need can be salvaged into Upgrade Stones: 10 stones per Skill card, 5 per Elite card, 1 per Option card. A card cannot be salvaged the first time you obtain it — only true duplicates.

Crafting Strategy

Crystals are the bottleneck, so spend them in the right order. First craft your class's Skill card — it is a guaranteed result and transforms your main farming skill. Second, fill your Option slots with cheap Type crafts (5 crystals each): even mediocre rolls beat empty slots, and at 1 stone per salvage the duplicates are nearly free re-rolls. Save Elite crafting for last and focus on Green (Ignore Defense) for PvP or Purple (Triple Damage) for damage builds — at 25 crystals per attempt with a chance of getting stones instead, Elite hunting is where your crystal stockpile disappears.
