plasma

Hot plasma.

Perfect

Plasma is a damaging gas that can seep through walls and other occluding objects, often destroying them in the process.

Mechanically, it is very similar to corrosive gas, except that:

• Plasma does 20 times more damage to creatures and robots.
• Plasma can leave creatures it comes in contact with coated in plasma, which causes an additional debuff.

Sources

Common sources of plasma, with their level and density, include:

Source	Gas Level	Gas Density	Reference
Plasma Gas Generation (plasma jelly has this at level 10)	Mutation Level	800 per turn, divided evenly into adjacent squares
plasma grenade mk I	1	40
plasma grenade mk II	1	80
plasma grenade mk III	1	120
plasma jelly (on death)	1	1000
spaser pistol (on projectile hit)	1	20 in cell hit, 10 in all adjacent cells
spaser rifle (on projectile hit)	1	80 in cell hit, 20 in all adjacent cells

Damage

The damage done by plasma depends on the target:

• Plasma deals damage to creatures and robots.
• Plasma deals significantly increased damage to:
  • Walls, doors, furniture, chests, statues, and similar objects.
  • brooding puffs.
• Plasma deals no damage to anything with the Item tag. This includes all weapons, armor, equipment, scrap, cybernetics, energy cells, garbage, food, trade goods, corpses, books, water containers, urns and vases, quest items, and most other similar items a character might carry around in their inventory. Furniture items, such as chests or weapon racks are affected, but any items within will drop to the ground undamaged.

Note that, even though plasma does not directly damage items, it does apply the coated in plasma effect to them. This can make those items more susceptible to other forms of damage, such as catching on fire.

The following damage formulas are used to calculate plasma damage:

	Formula	Notes
Creatures and Robots	( Density × GasLevel ) / 10	(rounded up)
Walls and Similar Objects	( 0.75 × GasLevel + 0.25 ) × Density	(rounded up)

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.

The density of plasma can get much higher than 100 with the Plasma Gas Generation mutation, which is the signature mutation of a plasma jelly. With that mutation, a creature releases 100 density units of gas into the cells around them each turn, and can continuously release gas for many turns depending on mutation level. This can result in very high density gas if the gas is released into a small area.

The following table indicates how much damage plasma of a certain level will do per round, depending on gas level and density. The table includes only Gas Levels 1 and 10, since other gas levels are not commonly found in game.

Gas Level	Density	Gas damage per round
		creatures / robots	walls / objects
1
	10	1	10
	20	2	20
	40	4	40
	60	6	60
	80	8	80
	100	10	100
	120	12	120
	180	18	180
	240	24	240
	300	30	300
	1000	100	1000

Gas Level	Density	Gas damage per round
		creatures / robots	walls / objects
10	50	50	388
	100	100	775
	200	200	1550
	300	300	2325
	400	400	3100
	500	500	3875
	600	600	4650
	700	700	5425
	800	800	6200
	900	900	6975
	1000	1000	7750
	1200	1200	9300
	1400	1400	10850
	1600	1600	12400

Looking for a more extensive damage breakdown? You can refer to the corrosive gas damage table - the numbers are the same except that you'll need to multiply the "creatures/robots" damage shown on the corrosive gas page times 20 to get the plasma damage for the same level and density.
