Luck

Effects

Good luck gives:

• Accuracy +3%
• Summoning +5%
• Concentration +5%
• Item generation +2%
• Increases land explored by 10% (bad luck just removes this bonus, it does not negatively impact explore)
• Dispel cost reduction of 10%
• Improves your odds with the item Deck of Many Things

Bad luck basically reverses the above.
