Once you enter a Round Battle and choose your attacking Element, you will have 30 minutes to clear the entire Round.

Element Days
The Elemental Hall goes through element specific cycles where one type of element is prominent in the hall. For a certain amount of time, all stones and orbs available as panel rewards will be the same as what element the day is. Before you enter the Elemental Hall, it will show you what element day it is and what effects it will have on the hall. It will also show you how long that element will remain. Once the timer runs out, the element will change and the perks will transfer to whatever element is shown. The Element will change each day in the following order [PASSION], [COOL] , [LIGHT] , [DARK].

Round Battle
Each round battle will enable you to encounter a variety of Archwitches. In order to participate in a round battle, the following number of Attack units are required in a given Elemental Unit:
 * Beginner → 2 Attack units in a given element
 * Intermediate → 3 Attack units in a given element
 * Advanced → 4 Attack units in a given element

Defeating enemies will cause treasure chests to drop and clearing the final round will enable you to unlock the treasure chests you received and obtain the rewards inside. If a Chimry Coin is among the rewards found in the treasure chests, you will have the opportunity to try a Panel Challenge. You will also earn Archwitch Subdue points for damage done to archwitches found in the Elemental Hall.

Sending your attack units into battle consumes Battle Points, and you can also use Battle Points to recover your Attack units. The following amount of battle points are required in order to recover your units:

This does not apply to other attack all skills. Also note that nullification skills can not block the Elemental Wave skill while in the Elemental Hall. The "Element Shield" will change each day in the following order [PASSION], [COOL] , [LIGHT] , [DARK].

Panel Challenge

Once you collect the Jackpot, it remains in the pool and the timer continues. You can continue to collect the jackpot until the timer runs out. You may only have 1 Jackpot at a time. Completing 6 stars with an active Jackpot will reset the Jackpot timer.

The Orbs and Stones available as panel rewards will change each day in the following order: [PASSION], [COOL] , [LIGHT] , [DARK]. (They will be the same element type as the "Element Shield")
