Heat is the mechanic which affects Smithing in the Mining and Smithing beta, affecting the forging and processing abilities. When first started in progress smithing objects start with 60 heat before any further heating in the Forge.
The amount of heat each item can hold is dependent on the player's Smithing and Firemaking level and with 99 in both skills the maximum amount of heat is 894. Visible boosts also apply. The exact formula is as follows:
MaximumHeat = 300 + 3x Smithing level + 3x Firemaking level
For reheating an item in the Forge the amount of heat per tick is also dependent on the player's Smithing and Firemaking level and with 99 in both skills the amount of heat gained per tick is 150. Visible boosts also apply. The exact formula is as follows:
Heat per tick = 50 + Floor(1/2 Smithing level + 1/2 Firemaking level)
The Progress needed to smith an item is dependend on the tier and amount of the bar used and the upgrade tier of the item.
|Bar||Progress Base [a 1]||Progress +1||Progress +2||Progress +3||Progress +4||Progress +5||Progress Decorated[a 2]|
|Elder rune bar||1000||800||1000||1200||1400||1600||800|
- ^ All numbers are the progress for one bar
- ^ The progress required is equal to the progress beede to smith the item.
While each swing depletes the remaining heat by 10 the progress gained depends on the remaining heat of the item.
|High heat (>66%)||2x|
|Medium heat (>33%)||1.5x|
|Low heat (>0%)||1x|
|No heat (0%)||No progress|
