Combustion Fraction

Combustion Fraction is an Inorganic Crop found on Elemental, Coal and Metal Worlds. It grows only on Gravel or Rock but has decreased seed drop and yield when planted near Rock. It has improved seed drop and yield when planted near Ancient Corruption.

Farming Kindling Mass requires level 3 in the Skill.

Harvesting
Unlike most other crops Combustion Fraction is a 3-D (Mesh) object. That means that it's easy to miss the top side of the hit box when using an AoE tool to harvest because the focus point lands on the front of the box, and the end result is an incomplete gather of the 3x3 block. The easiest way to get a clean harvest is to stand directly over the centre of the 3x3 block when striking.
