If you're new to RuneScape, you'll probably want to know what to
start off with, such as which skills to train or which quests you
should work on first. This guide will explain a bit about each
skill and explain which quests you should do first

Melee Combat: Now you would probably want to start
off with a weapon that can kill anything in one shot. That's not
going to happen, but the next best thing is a Scimitar or Battle
Axe. Each time you are able to wield a new metal type of weapon, go
for the next type of Battle Axe or Scimitar.
If you are willing to take a risk and sacrifice some defense to
cause some major hurt, Try a 2-Handed Sword. They are slow and you
won't be able to use shields. Also, try to level up Smithing, as
you might be a good enough smithy to make your own weapons and
armour. Try shops such as the axe shop in Port Sarim, or the sword
shop in Varrock.

Ranged: Start by getting around 100-200gp. Then go
to the Ranging shop in Varrock and buy a normal Shortbow. Spend the
rest on Bronze Arrows. Make your way south of Varrock to the small
farm with a shed and plenty of chickens and continuously pummel the
chickens with arrows. Be sure to pick up any that fall on the
ground after impact. It is optional to buy some leather armour to
start off with, but it's not the greatest idea when sniping
chickens.

Prayer: Put everything in the bank and switch to a
world (server) that has a small amount of people and head to
Varrock. Using your map, head into the Wilderness and head to the
chaos temple surrounded by lava. When I went, there was no one
around. There are around 20-30 continuous bone spawns, which will
provide a fair amount of Prayer experience when buried. If you
think you're ready, move on north to the bone yard. there are
Skeletons, but try your best to avoid them

Magic: Magic can be expensive to start with, but
when combined with Runecrafting (see below), it should be ok. Head
to the Wizard's Tower south of Draynor Village. If there are some
wizard's robes that are already on the floor, grab them. If not,
leave, or kill one (don't wear metal-related armor!) and grab some
blue robes.
If you have completed the Rune Mysteries Quest, grab a pickaxe, go
mine some Rune Essence, and obtain mind and air talismans. Then
craft some mind and air runes. If not, buy them from the Varrock
magic store. Cast wind strike as much as preferred on rats in
varrock sewers.

Runecrafting: You must have completed the Rune
Mysteries Quest before starting this skill. Go to Varrock with a
pickaxe, head to the magic store and ask to be teleported by the
shop owner to be teleported to the Rune Essence. Mine 28, head out,
bank it, then repeat until you have around 200-300. Head to Falador
bank and buy a mind talisman and an air talisman off another player
for a reasonable price.
Halve your rune essence that you mined and write that down. Keep
taking 28 essence at a time to the air temple south of falador and
craft air runes. Then repeat this with the other half of essence
except this time do it at the mind temple, north of goblin village.
Recommended to use these for magic.
