Pathogenic Plasmids Guide — Skill Trees & Shared Level Cap
Plasmids are part of Pathogenic’s metaprogression. Official updates introduced specialized skill trees for pathogen types, later reduced plasmid upgrade costs, and applied a maximum level cap shared across all plasmid trees.
What you need to know
Specialized plasmid trees
The Swarm update says each type of pathogen received its own plasmid skill tree so players can customize progression around the pathogen they choose.
Cost and cap changes
The Multi-Hit update says Plasmid Tree upgrades were made significantly cheaper and that a maximum level cap applies across all plasmid trees, with the cap itself upgradable.
Demo progress transfer
Before launch, the developers said accumulated demo plasmids would transfer to the full game, giving returning players a progression head start.
Common questions
Do all pathogens share one plasmid tree?
No. Official updates introduced specialized skill trees for pathogen types.
Is there a plasmid level cap?
Official Multi-Hit notes describe a maximum level cap applied across all plasmid trees.
