If you want to become an Ironman, you will have to talk to NPC Paul located on Tutorial Island – because of that, only new accounts can become an Ironman. After you arrive in Gielinor or, to be more precise, in Lumbridge, you can start leveling your skills. As getting through early stages of the game might be tough – especially if you don’t have any gold or items – you should buy runescape 3 gold consider doing some quests. Those can provide you with enough experience and items to have a decent start. Most notable among those is the Waterfall quest, which can take you all the way to 30 Attack and 30 Strength and can be completed on a fresh account that just left Tutorial Island.
To begin, you should complete quests that reward Crafting experience upon completion. Finishing Elemental Workshop 1 and 2 could land you around 12,500 Crafting experience with minimal requirements. The other way involves glassblowing on Entrana, which can be done by collecting Seaweed and making glass out of it. It can be an excellent spot to make some Crafting experience for both new and more experienced adventurers.
After hitting level 61 in Crafting, players should consider buying buckets of sand and soda ash from Trader Crewmember in Port Khazard. This location can be quite crowded, so if there are no items in stock, Catherby and Corsair Cove traders do have the same goods to offer. By smelting those in the furnace, you will receive molten glass used in the glassblowing process. By using a glassblowing pipe, you will be able to create Unpowered Orbs. To make this process even more simple, you can complete Hand in the Sand quest. It will make NPC Bert give you 84 buckets of sand every day.
An alternative way of leveling at this stage can be done by buying gold ores from Blast Furnace and smelting them into bars necessary to craft Gold Bracelets. Those will grant you vast amounts of Crafting experience and can be later dissolved with High Alchemy for a small profit and additional Magic experience.
As an Ultimate Ironman, your options are even less extensive. The best bet in this situation is to go to Port Phasmatys and bulk buy soda ash and buckets of sand. After that, you should head to the furnace located near the port and smelt them into molten glass used to make glass items. Always aim for the highest tier item. You can increase your skill level to maximize experience gains. After crafting your items, sell them to trader NPC and switch worlds to restock your source.
In the underwater area of Fossil Island, players can plant Seaweed Spores into the Seaweed Patches. By doing so, they will grow Giant Seaweeds. Harvesting these patches can be quite profitable since one Giant Seaweed equals six smaller ones. Adventurers who want to use this method will have to farm for Flippers, which drop from Mogres at 1/64 ratio.
Spores required for planting can be obtained from Lobstrosities, which reside nearby areas, so finding them should not be an issue. However, those who wish to kill them will need either Brine Saber or Trident. The first one can be acquired from Brine Rats (that do require 48 Slayer), and the second one can be gained from Kraken boss, which requires 87 levels in Slayer skill.

Players who completed the Lunar Diplomacy quest and are over 77 Magic level can cast Superglass Make spell. It lets adventurers craft without banking supplies. To train like this, buy buckets of sand and soda ash from Trader Crewmember in Port Phasmatys or any other place. Cast Superglass Make spell to craft highest level glass items that you can make. After your resources are depleted, make sure to hop worlds to refill them.
