Per her sig ability she has a 25% chance to enter limbo after filling 1 bar or power. This is based ona 5* with lvl 200 sig ability.
Why then does the 4* version in dungeons trigger limbo every single time she gets a bar of power?!?!
For that matter why does the AI champs trigger their abilities soooooooooooo much more often than the percentage would lead you to believe??? This being in any mode of gameplay except arenas.
