>>67176620 You now receive chip damage (tested to be roughly 30%) when blocking attacks, effectively changing your play style, requiring you to deflect perfectly.
Enemy vitality and posture is increased.
Regular enemies that would normally be
posture broken and vulnerable to a deathblow after a single mikiri counter will instead recover. (Needs further testing: seems like you do half as much damage, but so do things like the burning bull to the enemies in the arena).
You take 25% more vitality and posture damage, as well as receiving significantly more posture damage if you block an attack instead of deflecting.
Status effects, such as poison, build up roughly 40% faster. (Tested at poison pool for both charm and no charm. With Charm takes around 13.3 seconds to get poisoned, without charm takes around 7.8 seconds to get poisoned).
