Icarus Week 225 Update Adds Bull Cart Support and Limestone Deposits

Icarus Week 225 introduces cart compatibility for Bull mounts, adds Limestone Deep Mining Ore Deposits across all maps, and rebalances tool durability.

Icarus expands pack animal utility and material access in the Week 225 update. Bull mounts can now pull carts using an integrated skeletal mesh design, and Limestone Deep Mining Ore Deposits are now available across all main maps and outposts.

Bull Cart Integration and Mount Upgrades

Bull mounts join the Tusker and Buffalo in supporting resource carts. The cart skeletal mesh now incorporates the saddle directly rather than utilizing a separate pseudo saddle, fixing previous visibility and alignment issues. Slinker and Quick Tamer saddle support has also been added.

Map Expansion and Resource Access

Limestone Deep Mining Ore Deposits now spawn near water bodies on Olympus, Styx, Prometheus, Elysium, and all Outpost maps, granting alternative routes to mass concrete production. The Manufacturer bench can now craft recipes previously locked out, including rope, cupboards, wall torches, and window curtains.

Tool Durability and Balance Adjustments

Lithium tool sets have had their durability rebalanced to twice the highest tier equivalents, bringing tools like axes and pickaxes up while lowering others. The Chainsaw now features a unique durable row reducing durability from 500k to 180k, and the Nailgun durability was reduced from 13x to 1.5x of a Titanium Hammer. Additionally, creature experience inconsistencies and client hoverframe stutters have been addressed.

Why this patch matters

Week 225 delivers meaningful quality-of-life updates by bridging content gaps on older maps and smoothing out high-tier tool balancing.
