When choosing an attack style to kill things, some things are fairly common sense (following the combat triangle, for instance). Other times, deciding which attack style to use is harder to figure out. I find myself looking up each individual monster on the runescape wikia. After doing this for a while, I started wondering how the people that wrote those pages figured out what the weaknesses were of various monsters. The page on Mysterious Shades says that they have low defensive bonuses, but it goes on to say they are weak to slash. How were they able to determine this? Is this available in the knowledge base somewhere? Are they just going by what most people tend to believe? I'm trying to sort out what attacks to use and when, so I'm trying to get a better understanding of monster weaknesses and related matters. I recently dropped my prom maul for a 2h for the option to slash. I've seen lists of monsters that are weaker to slash than crush, but how did others figure out what was actually better to use?
