Critical Ring's "Instant Death"

However I think some of the monster's HP values were changed, I noticed while making one of my ring mules that the max level 3 snails skill (40 dmg) one hit kills red snails (should have 45 hp), I also remember that max 3 snails would not one hit kill red snails before... but now it does. So its possible they changed the monster's hp values for various mobs: Although unconfirmed.

I've noticed this too, I've been OHKOing level 27 white baby monkeys with 200s sometimes and other times they take a 900 and still have half HP left. Another 200 kills them, though. o_o
