 Description? 0.5% chance per rank when hit that the damage dealt will be reduced to 1. Does not stack with the equivalent Warpriest effect. Armour 5

Lucky is an Invention perk which has a 0.5% chance per rank when hit that the damage dealt will be reduced to 1. This perk does not stack with Saradomin or Zamorak warpriest armour. Lucky works on all damage types, including "combat" typeless. This means that it works on reflected damage and Helwyr's bleeds, but not Araxxor's cleave or Dwarven rock cake (cooled).

When the perk triggers, it prompts the following message with X replaced by the reduction: Your Lucky perk reduces the damage of this attack by X.

Lucky comes in 5 ranks, with the damage nullification chance shown below:

Activation chance
Rank Chance
1 0.5%
2 1.0%
3 1.5%
4 2.0%
5 2.5%

Given a monster's minimum $H_{min}$ and maximum hits $H_{max}$, and the rank of lucky $R$, the average damage reduction of the perk over $N$ hits can be calculated approximately as:

$0.005NR \times \max\left( \left( \frac{H_{min}+H_{max}}{2} - 1 \right),0 \right)$
