Just to add, poison ticks are based on target's max HP, the higher the max HP the higher the poison damage.
CB's max HP gets higher as the difficulty climb, so unlike other damage, where it gets lower as the CB difficulty hike, poison damage actually geo bigger, so as the reverse, while other damage gets bigger when you choose lower CB difficulty, poison damage gets lower
