Dragonfire

Dragonfire is the fiery breath attack used by most dragons, hence the name. It can deal considerable damage to players without an antifire potion in conjunction with an anti-dragon shield, dragonfire shield, ancient wyvern shield or dragonfire ward.

Overview
An adult dragon can deal up to 50 damage to players without the proper equipment. Regular armour doesn't offer any additional protection from the flames. However, there is a chance that the player will "resist some of the dragonfire", which usually causes the dragonfire to not inflict much damage when this occurs.

Normal chromatic dragons (green, blue, red, and black) only use close-ranged dragonfire attacks, meaning that the dragons will only use it if the player is in melee distance from the dragon.

Some dragons, like the King Black Dragon, brutal dragons (green, blue, red and black), Elvarg and metal dragons, have long-ranged dragonfire, and use it in both close or long-ranged combat situations. Metal dragon dragonfire is unique for not being reduced by Protect from Magic.

The King Black Dragon is able to use additional kinds of dragonfire besides standard, each with a different effect, including freezing, poisoning and stat-reducing. Vorkath also possesses different kinds of dragonfire; venomous, Prayer-deactivating, freezing, rapid-fire, as well as a slow but high damaging attack. Not having a form of dragonfire protection while fighting Vorkath can result in the player being hit for most if not all of their maximum hitpoints.

Baby dragons cannot use dragonfire.

Wyverns don't use dragonfire; instead, they use an ice-type breath, which is even more dangerous. It can reduce the stats of a player and prevent them from moving.

Protection
There are several methods to protect oneself against dragonfire. All methods apart from Protect from Magic require the player to have started Dragon Slayer to be used.

Using dragonfire
Players can also use dragonfire in combat, but only under one condition. The dragonfire used by players has the same effect as dragonfire used by dragons. Therefore, it can hit very high against players without proper protection.



One way to use dragonfire is by using enchanted dragon bolts in Ranged. These bolts have, like other enchanted bolts, a special attack. This special attack enables the wearer to occasionally hit the opponent with a blast of dragonfire, adding extra damage to a bolt hit (visible Ranged level * 20%).

Just like regular dragonfire, this methods will not cause damage if the opponent is a fire monster or a dragon. In PvP situations, if the opponent is wearing an anti-dragon shield, dragonfire shield or under the effects of antifire potions (or both), the special effect will not activate.

Magical fire is not considered as dragonfire. The protection needed for dragonfire doesn't provide protection against fire spells.

Players are able to discharge a blast of dragonfire with the dragonfire shield by right clicking the shield.

Trivia

 * The message when you are partially protected from dragonfire is different depending on what kind of protection you have.
