Every 10 minutes inside of The Diadem the weather will change. This\r rotates between normal weather and 'Umbral' weathers with Umbral weathers\r corresponding to a specific element and also spawn a unique node on the outer\r islands. These weathers are:\r \r \r Umbral Flare\r Umbral Levin\r Umbral Tempest\r Umbral Duststorm\r \r \r The weather itself is tied to each specific instance and can therefore not\r be calculated or known ahead of time. Umbral weathers are also the only ways\r for specific gatherable items to be available so these nodes are\r important.\r
