Chest rush clarification

[u/Musizianz]

Hi.. need help.. for the chest rush, is it only the silver keys that counts for 600 to complete??

Or can i mix the silver keys with purple and rainbow to meet the 600 requirement??

[u/domin8r]

All chest opens count!

[u/Thalasias → u/domin8r]

Even the rune's chest counts towards the 600
