Runesphere

The Runesphere is a Distractions and Diversions in the Runespan. Similar to a Shooting Star, it may have multiple layers and requires multiple people to successfully penetrate its many layers. Upon reaching the core you combine the essence dust you have obtained in the process with said core to get a big chunk of experience.

Each rune dust obtained grants 10 Runecrafting experience. You can only get a max of 1000 rune dust a day.

Runespheres also appeared during the See the Future teaser before the Runespan release. During the duration of the event, it changed elements before fading with the rifts that the event created.

Runespan Event
When a Runesphere is active in the Runespan an icon will appear at the top left of your screen, saying "Runesphere active". You then can find the Runesphere on one of the 3 floors at your world. It is not always located on the floor you are currently on, so you might have to go up or down floors to find it.

When you've found it you can start drawing runes and experience from it by siphoning it. When it first appears it has soul energy and only soul runes can be drawn from it by players with level 92 Runecrafting. Then when that layer is broken it will have blood runes, then death runes and so on until reaching air runes and breaking.

While siphoning the sphere, Rune dust will appear in your inventory which can be given to the ball of Pure energy that appears after breaking the whole sphere. You will get 10xp for every runedust you have.
