Do critical damage on wet monsters ( leechs always get 1 hit kill less 2* ones , these take 2 ) but not these were on a rain , the real wet debuff in monsters are when get a little swim in a little body of water
But make normal damage in almost every monster less in lox and trolls but them get slow frost debuff that is very good for crowl control ( thats why i think is far better than silver sword until u get black metal sword tier 4 )
Ah and do DoT on undead monsters as said above
