Weakness/Resistances

Some of your skills will have an icon to it, meaning it's an "elemental" skill.
That means, that this skill is strong against enemies that have this as their weakness. Here are pictures of what Icon means which element:
Description 	Icon
Against Females in general	
Against Males in general 	
Slime 	
Sadism 	
Masochism 	
Hotness 	
Cuteness 	
Dirtyness 	
Elegance 	
Weirdness 	
Kindness 	
Intelligence 	
Dominant People 	
Submissive People 	
So, if for example your skill has the 4th icon to it, that means it will be strong against enemies that are weak to sadism, an element that for example Tarius is good at using.
