In several fights with Goblins, we found that the enemy knows how to use primitively poisonous weapons. We need help producing anti-poision potions.
I need some blood serums, but for that, we need spiders' venomous sacs.
You'll find spiders near the grasslands cave in the northwest. Please help me collect their venomous sacs.
I have seen people poisoned by the Goblins. Their bodies rot away from the insides. It's horrid.
Venomous sacs increase the effects of blood serums, which are the only cure to the poison.
Be very careful!
