This describes 3 ways to earn Gralats in Graal.
Get a catching net, and catch bugs, flies and butterflies. You can then sell these for 50 gralats to a witch!
Find farming fields and start farming – you will get different gems, that are worth different amounts of gralats. This is second fastest way to make gralats!
Go kill pirates – you get gralats for each pirate that you kill. This is (arguably) the most time-effective or fastest way to earn gralats!
