[.981][UI Bug]World Difficulty Toolltip
The tooltip for world difficulty gives the information for AI difficulty levels but doesn't actually set base AI level anymore. It should tell you how it changes monster strength and behavior.
Also Expert strength seems not to multiply monster hp, while rediculous doubles hp growth and boosts experience gain. There is a huge diffrence between these two levels. Either this is a bug or expert needs to boost hp by 1.5 or something.
