Elemen
Pengenalan Elemen
Di RO, ada sepuluh Elemen berbeda. Beberapa serangan, seperti serangan jarak dekat dari monster, tidak memiliki elemen dan sama sekali tidak terpengaruh oleh pengubah elemen. Serangan seperti itu disebut non-elemen.
- Neutral - Properti Elemen Dasar. Sebagian besar skill/monster memiliki properti Neutral. Neutral tidak memiliki kelemahan elemen, tetapi properti Ghost tidak seefektif yang lain terhadapnya. Semua senjata, kecuali ditentukan lain, memiliki properti Neutral.
- Water - Kebalikan dari properti Wind. Water memberikan damage terbesar ke monster/armor properti Fire, dan paling lemah terhadap properti Wind. Senjata dapat ditempa dengan properti Water menggunakan
Mystic Frozen (995).
- Earth - Earth paling banyak menerima damage dari properti Fire, dan memberikan damage terbesar ke properti Wind. Senjata dapat ditempa dengan properti Earth menggunakan
Great Nature (997).
- Fire - Fire adalah kebalikan dari Earth, dan memberikan damage terbesar terhadapnya. Water memberikan damage terbesar ke monster/armor properti Fire. Senjata dapat ditempa dengan properti Fire menggunakan
Flame Heart (994).
- Wind - Wind lemah terhadap Earth, dan memberikan damage ekstra ke properti Water. Senjata dapat ditempa dengan properti Wind menggunakan
Rough Wind (996).
- Poison - Properti Poison tidak boleh disamakan dengan Efek Status. Skill Assassin
Enchant Poison dapat mengubah elemen senjata menjadi poison.
- Holy - Elemen Holy lemah terhadap elemen Shadow, dan memberikan damage ekstra terhadap elemen Shadow. Senjata dapat sementara di-enchant dengan properti Holy menggunakan skill
Aspersio milik Priest, sedangkan armor dapat diberkati dengan 
B.S. Sacramenti dan skill 
Piety milik Royal Guard.
- Shadow - Not to be confused with the Demon and Undead types. Shadow is the opposite of Holy, and does the most damage against it.
Cursed Water (12020) temporarily enchants weapons with the Shadow Property.
- Ghost - Ghost is only weak to the Ghost element.
- Undead - Undead elemental players and monsters can be damaged using the skills
Heal, 
Turn Undead, 
Resurrection, 
Sanctuary, and 
Highness Heal. Undead elemental players and monsters are also not affected by the knockback from the 
Fire Wall skill and are immune to Frozen and Stone status and the 
Provoke skill.
Damage Tables
In RO, Elements/id can be grouped into two types: attacking and defending. Defending elements are separated into four levels; the resistances and weaknesses of a defending element are amplified relative to its level. Attacking elements are not separated into levels.
Players have both an attacking and defending element, which are both naturally Neutral, but can be changed by equipping certain weapons and armor, using certain skills or items, or compounding certain cards. A player's defending element is always Level 1.
Monsters have only a defending element, but can inflict elemental attacks using skills.
Column is based on the attacking element and row is based on the defending element.
