What are the best quests for XP? I am new to thieving. Thanks

I'm assuming you haven't already done Fremmenik Trials, but that gives some healthy thieving xp and doesn't require a thieving level to start off with, so if you think you can, do that

The Feud gives the highest exp out of any quest (not including RFD or One small Favour)

Mourners end part I gives 20k.. but you should try Pyramid plunder. Deadly fast thieving experience.

Mourning's End Part 1 - 25,000 exp

 

The Feud - 15,000 exp

 

Contact - 7,000 exp

 

Darkness of Hallowvale - 6,000 exp

 

Icthlarin's Little Helper - 4,500 exp

 

Rat Catcher - 4,500 exp

 

Slug Menace - 3,500 exp

 

Fight Arena - 3,375 exp

 

Fremennik Trails - 2,813 exp

 

Fairy Tale Part 2: Cure a Queen - 2,500 exp

 

Death to the Dorgeshuun - 2,000 exp

 

Hazeel Cult - 1,500 exp

 

Biohazard - 1,500 exp

 

Tribal Totem - 1,250 exp

 

The Golem - 1,000 exp

 

Creature of Fenkenstrain - 1,000 exp
