WEATHER-MASTERY

Certain spells are affected by the weather. For example, fire spells do less when it is raining and lightning bolt spells do increased damage when it is thunderstorming.

Those with the Weather Mastery skill are able take increased advantage of positive weather elements to do greater damage. For example, a druid with Weather Mastery will do greater damage using lightning spells in a thunderstorm than those using lightning without Weather Mastery. Weather Mastery II further improves the benefits that Weather Mastery confers.

Weather Masteries increase the base environmental effects listed under ELEMENTS-AND-ENVIRONMENTS by multiplying that by:

 base environmental modifier * (Weather Mastery I + II) / 50

So for example, if a druid had 90% in Weather Masteries I+II and was casting a lightning spell in during a downpour (which gives a base modifier of 20%), their net modifier would be 20% * (90+90) / 50 = 72* ... i.e. this turned the base bonus from damage due to lightning in a downpour from 20% to 72%.
