Boss Sauce

Boss Sauce is a smoothie in Grounded. Its effect is Critical Hit Chance. In-game it is described as: "A critically acclaimed blend of the baddest bugs in the yard."

A smoothie: blend it at a Smoothie Station and its buff lasts a set time, so it is a pre-fight power-up rather than a snack.

The effect it grants is Critical Hit Chance — the reason to craft it is the buff it adds for its duration, not the item itself.

It is made from Wasp Queen Head, Broodmother Fang, and Mantis Head, so topping up your stock of those ingredients is the prerequisite for keeping a supply on hand.

Verdict: Overall Boss Sauce is a smoothie worth carrying for its Critical Hit Chance effect.
