You can try completing certain quests or participating in specific events related to it. Sometimes, rare drops from monsters might also give you a chance to obtain it.
I'm not entirely sure as I haven't specifically read a 'Red Tithe Novel'. It could potentially be about a story related to a red tithe, which might be a concept specific to the world of the novel, perhaps a form of payment or sacrifice in a fictional setting.
One good order could be starting with the Tutorial Island quests as they introduce the basic mechanics. Then move on to the Lumbridge quests which are relatively easy and build a foundation. After that, quests like the Vampire Slayer quest can be a good next step as it has an interesting story and unlocks some useful items and areas.
Well, in 'a tithe to hell fanfiction', perhaps the character development is really engaging. The characters may have to face their inner demons, literally, due to the setting of hell. And the way they adapt to the idea of giving a tithe could show a lot about their personalities and growth throughout the story.
First, do a lot of research on different concepts of hell from various mythologies and religions. This can give you a rich base for creating your version of hell in the fanfiction. Also, think carefully about what the 'tithe' means in your story. Is it a physical object? A service? A sacrifice of a part of one's soul? Then, create interesting characters who have different motives regarding the tithe.
I'm not very familiar with the 'Carcharodons Red Tithe Novel'. But generally, in Warhammer 40,000 related novels, they often explore complex themes such as loyalty, honor, and the fight against various threats in a dark and dystopian future. The Carcharodons as a group are known for their somewhat mysterious and often brutal nature. The 'Red Tithe' in the novel's title might be a central plot device that drives the story, perhaps related to resources, blood, or some other important element in the fictional world.
For a new player, start with the basic beginner quests like the Imp Catcher. It's easy and gives a feel for how quests work. Then, try the Witch's Potion quest which is also simple but starts to introduce more of the game's world. After that, the Dragon Slayer quest is a big step, but it has a great story and is a classic in the OSRS quest line.
Farm novels usually depicted one or more characters living on a farm. These novels often involved growing crops, raising animals, farm management, business operations, and so on. These novels were often light hearted, humorous, and fantastical because farm life was usually a simple and happy life in people's imagination.
Some farm novels had topics such as friendship, love, family, power, and loyalty. The protagonists usually experience many challenges and difficulties such as farm management problems, natural disasters, diseases, market competition, etc. However, they eventually overcome these difficulties through hard work and patience and achieve success.
Common farm novels included The Farmer, The Farm Home, and Animal Farm.
