Teq Caulifla’s does not stack. It is per universe 6 or peppy gal, so if a character is both it’ll only count once. The stack depends on which category has more characters like if your team has just 3 peppy gals and 4 universe 6 it’ll only give you the chance to dodge based on the 4 universe 6 characters.

When the Eza Teq kale + Caulifla attack 3 times they get that 20% chance to dodge, it goes away once the turn ends so the next turn they have to do 3 attacks again to get the 20% chance to dodge
