Elements
Elements Introduction
In RO, there are ten different Elements. Some attacks, such as the melee attacks of monsters, have no element and are completely unaffected by elemental modifiers. Such attacks are referred to as being non-elemental.
- Neutral - Basic Elemental Property. A large portion of skills/monsters are Neutral property. Neutral has no elemental weakness, but the Ghost property is not as effective against it as the rest. All weapons, unless specified, are of the Neutral property.
- Water - Opposite of the Wind property. Water does the most damage to Fire property monsters/armors, and is weakest to the Wind property. Weapons can be forged with the Water property using a
Mystic Frozen (995) .
- Earth - Earth is damaged most by the Fire property, and does the most damage to the Wind property. Weapons can be forged with an Earth property using a
Great Nature (997) .
- Fire - Fire is the opposite of Earth, and does the most damage against it. Water does the most damage to Fire property monsters/armor. Weapons can be forged with the Fire property using a
Flame Heart (994) .
- Wind - Wind is weak to Earth, and does extra damage to the Water property. Weapons can be forged with the Wind property using a
Rough Wind (996) .
- Poison - Poison Property should not be confused with the Status Effect. The Assassin skill
Enchant Poison can change a weapon's element to poison.
- Holy - The Holy element is weak against the Shadow element, and does extra damage against the Shadow element. Weapons can be temporarily enchanted with the Holy property using the Priest's
Aspersio skill, while armors can be blessed with 
Benedictio Sanctissimi Sacramenti and Royal Guard's 
Piety skill.
- 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 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.
