Bonfire

Bonfires are a method for training firemaking released with an update on 10 May 2012. It introduces the feature of being able to add more logs directly onto a fire.

This training method is available to members and non-members. This activity also gives strange rocks, and spin tickets.

Other players may add logs onto your fire, and everyone contributing will receive bonus firemaking experience for the logs added. Cooking on the fire will also provide boosts to cooking experience, and even gain the player health bonuses depending on the player's firemaking level and logs used.

Bonfires may last different lengths based on the type of logs used to create it. Depending on the type of log that was used to start the fire, the colour of the logs will be different. Bonfires will die away after a certain amount of time, even if you keep feeding logs to it.

Logs can be added to a bonfire in three ways: Just like when you chop down a tree, your player will keep adding logs to the fire without you needing to click constantly.
 * 1) Right click on the log and "Use" it on an already lit fire.
 * 2) Right-click on an already lit fire and select "Add-logs Fire".
 * 3) Open the "Craft" menu while standing near a fire and select "Add to bonfire".

Experience
Using logs with a bonfire instead of starting a new fire grants the following experience values. These values may change depending on your firemaking level. These also may be increased with the firemaking boosts detailed below.

Firemaking boost
Adding logs into a bonfire that is being used by more players grants a Firemaking experience boost compared to the basic experience for adding logs to one's own bonfires.

A significant boost is also obtained through utilising bonfires based on the player's firemaking level. For every firemaking level, the experience granted is boosted by a small, constant percentage. This effect is immediately noticeable when levelling up during training, as the maximum experience gained through burning the same logs instantly increases by 1 on many occasions.

This boost can be further increased by the aid of other items boosting Firemaking experience, like: the Ring of Fire, Flame gloves, the Dwarven Army Axe, the Barbarian Assault Penance horn and the Clan ring, though Summoning familiars do not add to the boost.

Life point boosts
After adding 5 logs of the same type, in a row, to a bonfire you will be given a boost to your maximum Constitution. The size of this boost depends on your Firemaking level and the type of logs you have used on your bonfire. The effect stacks with other life point boosts, such as those from Saradomin brews.


 * Cursed versions can also be added.

Cooking boost
Cooking on a bonfire you will receive a 10% boost in Cooking experience. This stacks with other boosts and bonuses to Cooking experience, like: the dwarven army axe and clan ring.

Fire spirit


Training Firemaking in this way also gives the possibility of finding strange Fire Spirits who'll reward you for freeing them from their wooden prisons.

The chance of freeing a fire spirit is not based on the type of logs used. It was confirmed that every log holds a 1/100 chance to release a Fire Spirit. Fire spirits last for fifty seconds before disappearing.

Upon freeing them, the player must click the spirit. The spirit gives rewards, usually some common runes, coins and various charms.
