In Mortal Shell 2, coins are a very useful resource, especially in the early game. To quickly farm money at the start, you can gather some Eavecap Mushrooms and take them to a Devouring Frog. Give it the mushroom, and it will reward you with a Swamp Pearl. Sell the pearl for a substantial amount of cash. After some time, when the frog starts coughing, you can repeat the process.
