14 coded traits that emerge from mutation or hybridization — each with real mechanical consequences.
Traits are not chosen — they are earned. A trait can appear through random mutation (influenced by Mutation Rate and gene profile) or be transferred at reduced strength during a Hybridization encounter. Each trait listed below is fully implemented in the simulation engine with precise numeric effects.
Each tick the simulation rolls a chance to mutate based on your Mutation Rate gene. When it fires, a trait candidate is selected weighted by your gene profile — you cannot choose which trait appears.
Your genes steer which traits are likely to emerge. A high-Aggression species tends toward offensive traits. A high-Resistance species trends toward immune and defensive ones. A high-Social species gravitates toward pack and swarm traits.
When two species hybridize, one can inherit a trait the other already carries — but at reduced strength. The transferred trait is marked with its origin species.
Some traits are gated by gene values. Pack Hunter and Swarm Behavior both require high Social scores to activate their primary bonuses. The trait can be acquired before the prerequisite is met but will do nothing until it is.
Makes your species significantly more dangerous in fights and in parasitic encounters. A venomous species also has a tendency to escalate shared-tile situations into outright combat, making it a naturally aggressive presence on the map.
Boosts combat effectiveness substantially, but only if the Social gene is high enough to reflect genuine coordinated group behaviour. A solitary species that somehow acquires this trait gains nothing from it — the group has to actually exist.
Rewards numerical dominance. The more your population outnumbers a rival in a shared tile, the bigger the advantage this trait confers. It also reflects cooperative foraging, giving a modest population growth bonus when the Social gene is high enough.
A well-rounded defensive trait that reduces losses in competition encounters and also offers meaningful resistance to disease. Pairs especially well with Spore Resistant for a species almost immune to infection.
Makes your species harder to find and engage. It reduces how often your species is selected as a target in multi-species tiles, and particularly helps when your species is in a weaker predator-prey relationship.
Accelerates health recovery after combat and hazard damage. Regenerative species do not need to avoid fights as carefully — they bounce back quickly and return to full growth speed faster than rivals.
The primary counter to infection-based threats. Offers the strongest infection resistance of any single trait and directly blunts the impact of the Spore Infector and Parasitic Brood traits that other species may carry.
A powerful offensive parasitism trait. When this species encounters a host it drains their population significantly — especially effective against hosts with low Resistance and no immune traits. The parasite itself gains from the interaction.
Goes beyond direct encounters. A Spore Infector species passively spreads infection load to nearby populations each tick without any formal encounter needed. It is a slow, map-wide threat that erodes rivals over time rather than in direct confrontation.
Dramatically improves survival and growth in Tundra and Mountain biomes. Without it, cold-biome strategies are a serious uphill battle. Species with high Climate Tolerance are the most likely to evolve this trait naturally.
Unlocks the desert and savanna as genuinely viable territory. Reduces the food pressure those biomes impose and raises growth rates there — but it comes with a tradeoff: the same adaptations that thrive in arid conditions work against the species in humid environments like swamps.
Makes island and coastal tiles, which are otherwise hard to hold, into strong positions. Essential for any strategy built around fragmented or isolated territory across the map.
Shifts the species into a different ecological time-slot. Nocturnal species encounter diurnal rivals far less often, dramatically reducing unwanted conflict. They also handle dangerous tiles better, making them surprisingly resilient in high-threat regions.
A coordination and signalling trait that pays off over time. Bioluminescent species grow somewhat faster (especially in intelligent lineages), get along better with neighbours during coexistence encounters, and are significantly more likely to successfully hybridize — making them natural bridge species in a diverse ecosystem.
