One Grub still gives 3 calories but costs 15 hydration.
In Rust, Grub is a food and drink in the Food category (item ID #-568419968, console shortname grub). In active play, it follows standard server rules for food and drink gear across procedural maps. Inventory storage stacks up to 25 units per slot, and uncollected ground drops despawn after 5 minutes.
A pale, fleshy insect that can be used for bait. Could also be eaten in desperate situations.
In Rust, Grub has no player crafting recipe; acquisition relies on map collection, smelting, or vendor trades read from the Rust game files. Monument recyclers do not break this item down into raw components, while it serves its dedicated role inside the Food catalog. Equipped and stored units carry no durability wear bar.
When comparing Grub against related food in Rust, prioritize farming its highest-probability monument containers or recycling surplus components at an unpowered radtown green recycler (fifty percent base yield, versus forty percent at safe-zone yellow units) because this item cannot be crafted at a player workbench.
