Are you looking for a complete guide for Biohazard Quest in OSRS? It’s a rather long and tricky quest, so a guide would come in handy.

Before You Cross the Border

Before starting the mission, you must first carry out the plague city mission. If you want to complete the task immediately, so that you can start performing the task, you should review other guidelines.

You will also need Priest Gown on the top and bottom, and a gas mask. If you want to get one for free, you can buy one at Edmond and Alrena's house in East Ardougne.

In addition, although it is not very strict, it is best to be able to transmit and possess some energy or endurance potions. They are worth OSRS gold medal you need to spend for your convenience.

With the Birds

To start the mission, you need to talk to Elena of East Ardougne. She will tell you to talk to her father's friend Jericho. He has been communicating with West Ardougne through pigeons, so it makes sense for him to ask you to adopt pigeon cages and feed birds. The former is behind the house, while the latter is in the cupboard.

Therefore, you will not be confused by the guide. Here are some background notes: The capital Ardougne is divided into two parts: East and West. As the name suggests, the latter suffered from the plague. If you have completed the plague city mission, you already know.

Go back, then you should talk to Omart. You will find him in the house of Ceril Carnillean in the southwest of the castle. He will tell you that it is difficult for you to enter the city because the guards are too close to the wall. To do this, you need to be distracted, which is why you must go to the small watchtower by the wall just north.

When you get there, move in the direction where the two fences meet. Poultry feed must be placed on any enclosure. After that, click on the cage. Then, Omat will call his assistant Kilron to give him the rope ladder. Climb it and you will reach West Ardougne.

Distracting the Mourners

After halfway through the capital and suffering from plague, he went to the mourner's headquarters. However, you will be barred from entering because they will eat stew. To enter, you need to distract them. how about it? Put a rotten apple on the stew cooked in the backyard. To get the fruit, you need to squeeze through the gap in the fence and then place the apple on the ground near it.

Then, the mourners will inform you that many of them are tortured by food poisoning and need doctor help. This is your reminder to go to the house of Nurse Sarah (National Sarah), which is in a building southwest of West Ardougne Church. There, you will find a medical suit. Wearing it, you can enter the mourner's headquarters. After entering, kill a mourner, find Elena's distillation chamber in one of the boxes, and then go to Kilron southeast of Ardougne in the west and return to East Ardougne.

Uncovering the Truth

n the next task, you will travel to Rimmington. It is best to send it to Falador, Draynor Village or cabbage patch. After reaching Rimmington, head to the southwest corner where you can find the pharmacist. He will give you the chemicals you need. You will hand them over to three errands, the gambler Chancy, the artist Da Vinci and the drinker Hops.

After that, equip a priest's dress and then head to the fenced area southeast of Varrock. You can buy 10 coins from Thessalia's Fine Clothes, or 12 coins from the owner of the Fancy clothing store in the north of Guidor. The guard will confiscate the vial, but confiscate plague samples. Take the plague sample, go to the Dancing Donkey Hotel, and chat with the three bottles you gave in small bottles.

After equipping the priest's dress, head to Guidor's house, which is located southeast of the exclusion zone. Give the vial and samples to Guidor and tell him that Elena needs samples. After confirming that the plague was a scam, return to Elena of Aduni and head to King Latias of the East Aduni Castle. Then he will introduce the whole conspiracy to everyone.

It is quite timely to carry out biohazard tasks these days. What are you waiting for? Pick up the mission now and buy RuneScape gold and experience the epidemic of Gielinor!
