Thieving guide

[Steven 35]

From level 1 - 20 you should thieve from the bakers stall for 875 xp per click, and can sell for 10k ea.

From level 20 - 40 you should either do the fur stall (1,250 xp and 5k ea) or the thieve's paradise minigame.

 

The specifics of the thieves minigame (highly recommended) are as follows:

 

Thieves Paradise:

Requirements: 20 Thieving (60 or 80+ highly recommended)

To get there: Minigame Teleport > Next page > Thieves paradise

Chest locations and requirements/rewards:

South-East: Level 20 | 250 experience per loot | Bronze Key worth 25 points

South-West: Level 40 | 2,875 experience per loot | Iron Key worth 50 points

North-West: Level 60 | 4,375 experience per loot | Steel Key worth 75 points

North-East: Level 80 | 7,625 experience per loot | Silver key worth 100 points

 

Keep in mind that if you're looting the level 80 chest there's a chance you could be teleported to barrelchest. He is absolutely worth fighting as he always drops 5 silver keys (500 points) and has a chance of dropping barrelchest anchor which can be sold to the general store for a decent amount of money. (Remember to take some prayer potions and food, he can disable your overheads and hits hard)

To turn your keys in for points, just teleport to theives paradise and look to the west, there should be a Magic chest there, if you click on it with keys in your inventory, you'll receive points.

To use your points: Speak to Johanhus Ulsbrecht and click trade.

You can view your current points in your quest tab ("Thief points" Remember to hit the refresh tab next to the achievements icon for an accurate count.)

The level 80 chest has a chance to teleport you to the Barrelchest boss. 

You can safespot it using this method:
