cleansing is a pulse of reduction every 50 frames, so the remaining duration of curses after flat resist is reduced by the pulse% every 2 secs.
60 sec curse
50% resist
50% cleansing
reduces to 30 sec dura then cleansing reduces that 30 sec by 50% each 2 secs
after 2 secs, duration = 15 secs
after 4 secs duration = 6 secs
after 6 secs, duration = 2 sec
after 8 sec, its gone.
not very useful vs IM.
SoB works the same way. It was OP before because it had no delay, so was cutting the duration by 60% 25 times a sec
