Defence

Defence is a skill that gives player protection. As a player raises their Defence level, opponents will deal damage less often. Defence does NOT influence the amount of damage that will be taken. Defence levels also affect what kind of armour a player can equip. The current minimum to be ranked in Defence is Level 60 and experience.

For non-members to get 200+ defence bonuses against stab, slash, crush and ranged at the same time they need to equip the following: A rune platebody (you could use a rune chainbody, but the defence bonus would not be so great, an adamant platebody will also work), rune plate legs/skirt, rune kite shield, rune full helmet, fighting/fancy boots, green dragonhide vambraces, an amulet of defence, a cape (any colour) and a weapon that does not too severely decrease any of the defence bonuses.

Fighting defensively
To increase a player's Defence level, they must choose the "defensive" attack style. To do this, a player has to click on the image with the two swords beside the menu that shows their skills. This menu is called the "attack style menu". The player can then click on the attack style that says "defensive" in brackets.

While fighting defensively, players will not be hit as often as they would when fighting aggressively or accurately and when they are, the damage is reduced, to the minimum of 0, making it as if the player was never hit by the attack. Fighting defensively will also reduce how often you hit and how hard you hit.

Strategy
Having a high Defence level is key to any fighter's success. If one wants to land strikes, one has to also be able to take them. The Defence skill lowers the frequency of opponents' attacks landing and causing damage, countering the opponent's attack skill and by extension their strength.

Numerous players, especially melee-pure player killers, neglect their Defence in favour of training Attack and Strength or Strength alone. Often, Defence is left at level 10, so as to enable the wearing of popular black armour. Though this strategy gives a person high power in their attacks, it is not recommended. Even if a person in the wilderness boasts very high Attack and Strength levels, if they do not have the ability to wear (or do not possess) decent armour, a person of a comparable level with high Defence may kill them with little or no trouble. Therefore, it is becoming increasingly popular to train defence to at least level 40, as to enable the player to wear the ever-popular rune armour.

Experience
A formula is used that decides how much experience a player obtains when fighting defensively. If a player hits an opponent, whatever damage they deal is multiplied by 4 and given to the player's Defence skill. For example, if a player hits a 1, then they will receive 4 Defence experience.

Some experience is also given to a player's hitpoints level when they deal damage. If a player hits an opponent, whatever damage they deal is multiplied by 1.33 and given to their hitpoints. For example, if a player hits a 1, then they will receive 1.33 hitpoints experience, in addition to the 4 experience in defence.

If a player fights with the "controlled" attack style, then whatever damage they deal will be multiplied by 1.33 and given to the player's Defence, Attack, Strength, and hitpoints level.

Defence can also be trained by ranging in the "long range" attack style. For every hit dealt to the opponent, players receive 2 range experience, 2 defence experience, and 1.33 hitpoints experience.

Defence can also be trained by attacking with magic spells while autocasting with a staff with a defensive cast style. Doing so gives players 2 experience points to magic and 2 to defence, as well as the 1.33 to hitpoints.

Defence bonuses
Some weapons and armour give players "defence bonuses" against certain attack types. These bonuses can be seen in the equipment menu, to the right of the inventory menu. Defence bonuses give players advantages as well as disadvantages in combat.

Stab: Wearing melee armour lowers the chance of players stabbing with a weapon from dealing high damage. The higher this bonus is, the less often an opponent will deal damage by using the stab attack style. The maximum possible bonus attainable by players is 387.

Slash: Wearing melee armour lowers the chance of players slashing with a weapon from dealing high damage. The higher this bonus is, the less often an opponent will deal damage by using the slash attack style. The maximum possible bonus attainable by players is 395.

Crush: Wearing melee armour lowers the chance of players crushing with a weapon from dealing high damage. The higher this bonus is, the less often an opponent will deal damage by using the crush attack style. The maximum possible bonus attainable by players is 377.

Magic: Wearing ranged armour lowers the chance of magic attacks dealing high damage. The higher this bonus is, the less often an opponent will deal damage by using Magic. The maximum possible bonus attainable by players is 201.

Ranged: Wearing melee armour lowers the chance of players using ranged weapons from dealing high damage. The higher this bonus is, the less often an opponent will deal damage by using Ranged attacks. The maximum possible bonus attainable by players is 414.
