As the receptionist explained, if the objective of the mission was only at the outermost part of the Wailing Forest where only the weak or low-grade beasts were present, it can be commissioned for a gold coin but going further inside would increase the price.
Apparently, a larger number of Evil Beasts were lurking around that place, and if the Hunters were not careful, they might even die. Luckily, the objective was only to take a small branch of the huge tree and a specific Hunter that has Stealth Magic Equipment can easily do this without much trouble
"Actually, the price is already extremely low…" The receptionist said as she further explained.
People may say that a mission that rewards only a single gold coin to ward off or kill a low-grade beast was extremely low. However, sometimes, it wasn't about the reward of gold coins but the contribution you make to get a higher rank.
