Legendary Bosses

Legendary Pokémon can occasionally spawn as the Raid Boss during Hard and Wildcard mode raids. They function as the rare high-value outcome of the standard raid system, giving players a chance at raid-exclusive species, Shiny Legendaries, and Hidden Abilities.

The chance for a Legendary Boss is dependent on the Difficulty Tier, size of the raid party, and the Legendary Pity value of each party member.

Party Size	Chance Bonus
1	0%
2	5%
3	10%
4	15%
5	20%

Legendary Boss Chance Formula

$\begin{aligned} P(\text{Legendary}) &= \frac{ \sum_{i=1}^{n}(1 + p_i) }{ n \cdot d \cdot (1 - b_n) } \\[0.75em] \text{where } n &= \text{party size},\\ d &= \text{difficulty tier base chance denominator},\\ p_i &= \text{legendary pity of player } i,\\ b_n &= \text{party-size bonus for a party of size } n. \end{aligned}$

$b_n \;=\; \begin{cases} 0 & \text{if } n = 1, \\ 0.05 & \text{if } n = 2, \\ 0.10 & \text{if } n = 3, \\ 0.15 & \text{if } n = 4, \\ 0.20 & \text{if } n = 5. \end{cases}$

Legendary Pity

Each player builds Legendary Pity by completing Hard and Wildcard Raids that do not become Legendary Raids. Once a Legendary Boss is spawned, the pity values of the participating party members are reset.

Here are some example scenarios for a Platinum raid, which has a base chance of $\frac{1}{400} = 0.25\%$.

Party Size	0 pity/player	5 pity/player	15 pity/player
1	$0.25\%$	$\frac{1+5}{1\times400} \Rightarrow \frac{1}{66.\overline{6}} \approx 1.5\%$	$\frac{1\ +\ 15}{1\times400} \Rightarrow \frac{1}{25} \approx 4\%$
2	$0.263\%$	$\frac{(1+5)+(1+5)} {2\times380} \Rightarrow \frac{1}{63.\overline{3}} \approx 1.57\%$	$\frac{(1+5)+(1+5)} {2\times380} \Rightarrow \frac{1}{23.75} \approx 4.21\%$
3	$0.277\%$	$\frac{18}{3\ *\ 360} \Rightarrow \frac{1}{60} \approx 1.66\%$	$\frac{48}{3\times360} \Rightarrow \frac{1}{22.5} \approx 4.44\%$
4	$0.294\%$	$\frac{24}{4\times340} \Rightarrow \frac{1}{56.\overline{6}} \approx 1.75\%$	$\frac{64}{4\times340} \Rightarrow \frac{1}{21.25} \approx 4.7\%$
5	$0.312\%$	$\frac{30}{5\times320} \Rightarrow \frac{1}{53.\overline{3}} \approx 1.87\%$	$\frac{80}{5\times320} \Rightarrow \frac{1}{20} \approx 5\%$
