Icarus Update 2.3.27.147460 Streamlines Base Lighting and Previews Creature Genetics
The Icarus Lights Update consolidates wall and ceiling fixtures, adjusts creature experience yields, and lays the groundwork for animal genetics and breeding.
The lights update for Icarus combines multiple lighting variants into unified recipes, rebalances creature experience gains, and introduces the foundational systems for upcoming animal breeding features.
Lighting Consolidation and New Fixtures
Wall and ceiling light variants have been combined into single items using hold-R toggles to reduce recipe clutter. New Shroud Light and Spotlight items are now available on the tech tree, and existing lights feature adjusted stacking limits and weights.
Creature Experience Rebalance
Experience rewards for numerous creatures have been adjusted. Values for entities like Glaci, Scorpion summons, Terrenus, bees, trapjaws, orkas, slinkers, and various raptors have been updated to rebalance progression pacing.
Spider and Drone Adjustments
Spiders no longer spawn at caves if a player is within 50 meters, and cave spider poison chance and damage have been reduced. Drones now feature a flat 50 percent chance to drop electronics alongside a 1 percent chance for powerbanks.
Foundational Genetics and Husbandry Systems
The update introduces underlying systems for creature genetics and animal husbandry. Tames and mounts can now inherit attributes across stats like vitality, endurance, and muscle, with visual skin variations and breeding mechanics implemented for future activation.
Why this patch matters
Update 2.3.27.147460 successfully cleans up base decoration management while rebalancing experience gains and paving the way for deep animal breeding mechanics.
