The more braziers that are lit, the faster the meta will progress when the progress bar shows up. It's ~45 minutes from the previous meta to the beginning of the progress bar.
The closer it is to meta time, the more braziers will become under attack. When the meta begins, 9 champions will randomly spawn at a brazier. Make sure to check the map!
There are two events:
"Gather stone to bolster the statue of Chokocooka" (gathering event) & "Protect the statue from destruction" (defense)
If the gathering event completes, then the defense event will spawn ~8:30 minutes later. The defense event, if successful, will continue the defense event rather than the gathering event.
There are two events:
"Destroy all the icebrood around the hot springs" (Icebrood) & "Clear the streams of corruption so the quaggans can enjoy bathing" (defense)
If the Icebrood event completes, then the defense event will spawn ~5:00 minutes later. The defense event, if successful, will continue the defense event rather than the Icebrood event.
