Code:
Self-Reflection
Channeled
The Sha of Pride causes up to 5 players to reflect on their actions, creating a Reflection of Pride at their location. With each tick of Self-Reflection, the Sha focuses on players with higher levels of Pride, only targeting those with 25, 50 and then 75 Pride.
It seems to create 5 adds for each "group" of players it targets.
On the first Self-Reflection you're probably all sub 25 pride, meaning you only have 1 "group" of people that can spawn adds - hence only 5 spawn.
Suppose you have 3 members >25 pride, the rest below - I guess this would spawn 8 (5 for those below 25 pride + 3 for those above) Reflections.
So if you have 4 players below 25, 3 between 25 and 50 and 3 above 50 you could probably spawn 10 adds I'd think.
