Hello. I have also reached the Fallen Knight from Floor 200 and noticed the same as well.
I do make around 1k-3k dmg to him, but it seems that he takes damage only if my totems hit from a larger distance.
Each time the boss is close to the totems or me it is always 0 damage.
Another thing is that the damage is only a around 5% to the boss and then he doent take any more damage. I have also do the fight by sommening totems and evading his skill for more than 10 min and he had the the same health without moving and taking constantly 0 damage.
How about the other monsters in floor 200, still 0 damage?
Only boss Is 0 damage, small monsters in 200F is up to 5000 damage per hit.
@Dylan Ang Wee Yong have you tried to remove totem rune?
@gu kun remove also same problem.
