Swarm Infection

Mod adds Infection of the Swarm
Meteorite drops on earth, carrying Swarmers
Swarmers are amalgamations made up with flesh of the aliens they had assimilated.
Swarmers attack any living creature, dissolving their flesh and turning it into biomass, they then merge with that biomass and become Amalgamated
Amalgamated can evolve and create more swarmers

the mod adds a point system that increases with actions of Swarm Infection
Higher the phase, higher the difficulty

Mod has multiple tiers of mobs

Swarmers: the start of the infection, they attach themselves to the mobs and merge with them

Amalgamated: the result of swarmer merging with their victim, can evolve into different variations

Grown: evolved variants of Amalgamated they get new abilities and strengths, can grow even bigger after killing enough mobs

Overgrown: even stronger variants of Grown, they mostly have the same abilities, but they are better or some of the overgrown could have new attributes

Nodes: mass of biomass that spread around the ground
they can grant the Infection poition effects to make them stronger

Leviathans: created from nodes, they are large constructs of biomass that destroys everything on their path
they act as main bosses of the infection

Point system

When the infected kill something, evolve, or create more of themselves they gain points
with certain threshold it will increase the phase

phase 0
before the infection start
no infected spawn
you cannot go back to phase 0

phase 1
will trigger after the meteorite crashes on spawn
swarmers will naturally spawn

phase 2
more swarmers spawn
amalgamated start to spawn naturally
leaders have a chance to spawn instead of a normal variant

phase 3
some infected gain permanent effects
grown start to spawn

phase 4
gained permanent effects are stronger
Overgrown start to spawn naturally
Nodes may start to spawn after overgrown kills enough mobs

phase 5
even stronger gained effects
nodes start to spawn really rarely
there must be an 800 block distance from another node to spawn another node from overgrown kills

phase 6
nodes can now start spawning leviathans
