1) The addition of elemental spirits, like the Sadeir (Farahdeen). These entities would be a type of custom mob that's basically blazes with a different skin (snow-style skin for Winter Elementals, Desert Skin for Sand Elementals, ext) and would not do fire damage.

2) Less rain/snow on all worlds, but especially Jorrhildr because snow lags my computer like no ones business lol
