You won't be able to buy logs, ores, or food from other players, so your skilling setup must be self-sustaining. Start training these key resource-gathering skills right away:
Woodcutting & Firemaking

Train Woodcutting by chopping regular and oak trees.

Use logs for Firemaking and Cooking fires.

Progress toward cutting yews for Fletching and long-term cash via High Alch.

Mining & Smithing

Start with copper and tin in Lumbridge or Varrock.

Smelt bronze bars to make early gear.

Progress to iron and steel for better weapons and armor.

Fishing & Cooking

Fish, shrimp, and anchovies in Lumbridge or Draynor.

Cook them to begin stockpiling food.

Work toward catching trout and salmon in Barbarian Village, then tuna and lobsters later.

Herblore

Unlocked via Druidic Ritual.

Start collecting herbs and secondary ingredients.

Early potions (Strength, Prayer, Antipoison) give huge advantages in combat.

Crafting

Kill cows for hides, tan them, and craft leather armor.

Train early, crafting while saving hides for future gear.

Gathering and training these foundational skills ensures you have consistent food, armor, and money-generating options.

Train Combat with Efficiency

You won't have access to gear from the Grand Exchange, so combat leveling must be efficient and resource-driven. Here's how to get started:

Best Early Combat Targets

Chickens and Cows: Provide feathers, bones, and hides.

Goblins: Easy targets with small coin and armor drops.

Al-Kharid Warriors: Drop runes and provide solid early XP with better defense gear.

Stronghold of Security: Offers XP, a safe training area, and a 10,000-coin reward. Prioritize this early for both money and training.

Every player needs a lot of RuneScape gold, I suggest you go to a third-party website like RSorder.com to buy, safe and comfortable transactions, and years of experience to ensure the security of your account.
