Thieving/Moneymaking

Thieving is one of the current, as of v1.0.2, best ways to make money. With all the best setup, you can reach up to 16.47M gp/hr.

This page was last updated for (v1.1).
The targets and numbers here are not updated, but gear and obstacles are ok

Early on, the bonuses might not be very good, but getting the Mastery level up to 99 increases the stealth by +75. Any amount of stealth makes a huge difference. Look forward to this.

The best target is eventually the Knight, with the King and the Princess coming really close. If using the Devil synergy, the princess is actually better than the knight, but not overall.

Until you reach higher levels, stick with Merchant, Bob the Farmer or Fisherman, as they provide decent gold (around 2 M/hr) per hour.

Gear

If you have the passive slot, using both gloves is great. Keep in mind that some of the latter enemies do require some   Damage Reduction.

While not all obstacles have an effect on   gold gain, all relevant pillars are here because of experience effects.

The pillar of Obstacle 4, both pillars of Obstacle 5, and Ice Jump of Obstacle 9 give gold gain effects. Use the Pillar of Generosity for gold.

Other effects

  Gentle Hands Potion IV Increases stealth. Higher success rate.
  Snek +50% bonus to GP gain. With all the bonuses this doesn't make much of a difference.
  Mister Fuzzbutt +5% GP. Nifty.
  Aquarias +1% double item chance. Does not hurt, but minimal bonus.
  Astrology Chance to double loot, and minimum GP by 11%. That's good.
