Overview

A Bonfire is a pile of wood in the form of a building. Wood can be removed from, and added to, the bonfire at any time; the pile will remain as long as some wood is left. The size of the bonfire varies depending on how much wood is in the pile.

Bonfires may be lit, which eventually consumes all of the wood and leaves behind a quantity of charcoal. This is a highly inefficient, if entertaining, method of charcoal production. Lit bonfires figure prominently in the Festival of Ra.

Not to be confused with the Sacrificial Bonfire used in the Test of the Vigil.

This building becomes available with Controlled Burn technology. It is built outside through the Projects -> Misc menu.

Use

Bonfires are commonly left unlit and used for wood storage. As their size is dependent on how much wood is in them, it's advisable to place them in an area where they have room to grow.

Lit bonfires consume wood at an accelerating rate, until the wood level reaches zero; the fire dies shortly afterwards. As the flame burns, you can add water to the bonfire to slow the rate of consumption; this helps the fire last longer, but doesn't seem to affect charcoal production.

You can tear down a bonfire while it is burning. This extinguishes the fire, and you will recover all of the wood that had not been burned yet. You will receive no charcoal for any wood that had been consumed.

Charcoal

The payoff for charcoal from bonfires seems to be extremely limited. It appears that yield is based on a very simple formula of #cc = #wood/10, with any remainder dropped. So, 10 wood will produce 1 cc, as will 11, 12, ... 19. 20-29 will produce 2 cc. And so on.

Here are some observed yields:

# wood	cc yield
7	0
10	1
14	1
20	2
30	3
35	3
42	4
49	4
56	5
63	6
100	10
250	25

Size

I think it's not important for most of us, but here is the equation for wood needed for given size:

Wood = Size^2

Simple. For size 1 we need minimum 1 wood. To make the bonfire 1 size larger you need to add 3 wood for a total of 4 wood and so on...
