defoliant

The synthetic mist called Golden Dawn ascends from its canister to atomize leafage and leave a clear view of the horizon in its wake.

Defoliant is a type of gas that is a damaging to plants and to objects composed of live plant matter. defoliant can seep through walls and other occluding objects.

It can also damage worn equipment (such as a vine-weave tunic), but does not affect items held in the inventory.

Sources

Common sources of defoliant, with their level and density, include:^[1]

Source	Gas Level	Gas Density	Reference
defoliant pump	1	4d104-40 (Avg: 22) in each cell that a pump projectile passes through 8d108-80 (Avg: 44) in each cell where a projectile hits a solid target 5 projectiles fired per shot, gas emissions from each projectile stack	^[2]^[3]

Damage

The damage done by defoliant depends on the target.^[8] For a more detailed breakdown of the types of targets listed here, refer to the Objects Affected section below.

Defoliant deals damage to photosynthetic creatures and to mutated plants. Mutated plants more or less encompasses all plants that are combat-capable and have faction associations.
Defoliant deals significantly increased damage to all other plants, generally meaning any sessile plants that are not capable of combat and do not have faction associations.
Defoliant deals significantly increased damage to objects composed of live plant matter.
Defoliant deals no damage to anything else.

The following damage formulas are used to calculate defoliant damage:^[8]

	Formula	Notes
Photosynthetic creatures and mutated plants	( Density × GasLevel ) / 200	(rounded up)
Sessile plants and plant-matter objects	( 0.75 × GasLevel + 0.25 ) × Density	(rounded up)

In theory, this means that a typical cloud of defoliant gas (~100 density) will deal approximately:

1 damage per turn to mutated plants.
100 damage per turn to sessile plants or objects composed of live plant matter.

In practice, gas damage is highly variable due to a significant amount of randomization involved in gas behavior. Gas is constantly moving between cells, dissipating over time, merging with other gas, and being affected by random calculations in the game engine. Its density, which is the main predictor of damage, is always changing. For more information about the mechanics of gas behavior, visit the Gas page.

The density of defoliant can get significantly higher than 100 if several sources of it are combined, such as multiple defoliant grenade mk IIIs or successive shots from a defoliant pump. Because defoliant can seep through walls, however, it will not be contained by enclosed rooms or tight hallways - it will continue to spread and dissipate after it is released.
