A Calamity targeting a player will cause the Mycophobia track to begin.
Calamity Mobs
General Spawning
Spawned from a Womb when it reaches 100 biomass. Depending on where a Parent Signal occurred will change what class of Calamity results from the spawned Womb.
If no specific conditions are met for a Parent Signal, it will result in a Land Calamity.
If a Parent Signal occurred at or below Y=63, it will result in a Ground Calamity.
If a Parent Signal occurred at or below Y=70 and, in a 14x14x14 block area around the Parent Signal, there are 7 or more Water Blocks, it will result in a Water Calamity.
If a Parent Signal occurred at or above Y=90, it will result in an Air Calamity.
There's a 30% chance that the Womb will spawn the incorrect Calamity type.
Tier-Unique Mechanics
Rooting
Calamities can only become Rooted if they have 0 Kill Points, are below 30% health, and don't currently have a target. While Rooted, they become stationary. For every minute they are Rooted, they will gain 1 Kill Point. If at any point, any of the three parameters are not met or the Calamity is damaged, they will unroot.
Air Calamities will sometimes land when idle, so they aren't excluded from the Rooting mechanic.
Adaptation
All Calamities are capable of Adapting, which occurs under specific circumstances (or if the Calamity is spawned during Proto World Modifier) and either buffs basic stats of the Calamity or will grant them a new ability (e.g. if a Gazenbreacher spends enough time in lava, she will gain her Crispy Adaptation that chars the texture and makes her immune to fire damage). Each Calamity only has one Adaptation.
Spore Bursts
While having a target, there is a 0.3% chance every tick for a Calamity to perform a Spore Burst. It can only be successful if their target is within ~14.4 blocks. Additionally, there's a 20% chance for a Spore Burst to activate when a Calamity takes freeze damage.
When first activating a Spore Burst, the performing Calamity will be unable to move for 3 seconds. Spore Bursts will summon a Scent at the location of the Calamity, give various positive effects to nearby Infected, Evolved, Hyper Evolved, Experiments, Bairns, Scampers, and Gastgebers, and give various negative effects to nearby non-Spore living entities. The range for giving effects is 16 blocks, and the effects granted depend on the Calamity activating the Spore Burst. Spore Bursts grant 0 to 3 Kill Points to any applicable Mobs within range. Additionally, if there are any CDUs in range of where the Spore Burst occurred, they will become clogged, meaning they no longer work. They can be fixed by breaking them and placing them back down.
Combat Scents
While this mechanic is similar to Spore Bursts, it's different. While having a target, there is a 0.25% chance every tick for a Calamity to summon a Scent at the location of the Calamity.
Summoning Vigils
If a Calamity is below 50% health and has a target, there is a 0.5% chance every tick for the Calamity to summon a Vigil within a 20 block range. The Vigil's parent will be set to the Calamity that spawned it.
Corpse Pieces (WIP)
When killed, multiple Blocks of Biomass, Blocks of Calcified Biomass, Blocks of Sickened Biomass, Rooted Biomass, and Human Remains will appear as falling entities where the Calamity died and fall to the ground. The only other mob that can do this is the Proto Hivemind, which places different blocks. Additionally, multiple Corpse Pieces will fly out from the Calamity.
Each Calamity has a set amount of Corpse Pieces they can drop, however it's only a chance for a specific Corpse Pieces to drop. The chance depends on the Calamity, and the values are listed below. These Corpse Pieces carry the regular drops of the Calamity, which can be harvested by either left or right clicking on the Corpse Piece. The last drop from a Corpse Piece will always contain a Reforged Biomass. When right clicking using a Reaver per instance of harvesting items, there will be a 30% for a Reforged Biomass item drop, regardless of how many items are left in the Corpse Piece's internal inventory. If a Corpse Piece isn't collected after 5 minutes, it will disappear and place down multiple Human Remains in its place, or a 10% chance for an Age 1 Mound.

Trivia
Calamities are the strongest mobs in the mod and it will remain that way; nothing stronger will be added.
Some Calamities have Christmas textures that activate in December (e.g. The Santa Sieger, which is wearing a Santa hat).
All Calamities have genders and sexualities (e.g. the Sieger uses they/them pronouns). This was first done as a joke for the Sieger, due to it being made up of multiple bodies, but it was then applied to every Calamity.
Due to how Calamity deaths are handled, they are not properly tracked in the Minecraft milestone menu.
The Hohlfresser's Corpse Pieces have a 100% chance to spawn because the creator of the mod needed to get all the segment variants and inflation values right.
The Corpse Pieces for the Galleon Grakensenker appear the same as its un-Adapted counterpart. This is because Corpse Pieces do not support custom models, and thus have to remain the same.
In non-public versions of Spore, when the mod creator was making the Sieger, every time it got a kill, it would get 10% of its health back. This was before the Kill Point system was implemented. This mechanic would've existed for every Calamity. It was scrapped for being too powerful.
Early in the mod's development, an idea for a Calamity comprised mostly of Braiomils that would've been deadly to get near could've made it into the mod. However, it was scrapped for unknown reasons.
