A new addition in update 4.0, previously the weekend boss rush was designed for grinding coins, and it lasted from friday to Sunday, after the update, we now have a daily boss rush. Like the Elemental runs each day, using that days element hero will increase damage to enemies +30%. The event has shrunk from 12 rooms to 10 rooms, with one time clear awards at room 5 for 10200 coins and room 10 for 20400 coins.
Runs cost 4 energy and there is one attempt available per day with 1 recharge of 1 attempt as well
Possible drops: common items, coins, rainbow materials
Each day the rooms are themed to the element, unlike the old weekend boss rush where it was the same each week.
This increases the daily runs from 4 to 5, using 20 energy each day to complete all dailys each day.
