Flaunt your powers and embark on a journey to challenge other Summoners of the land! Destroy all that stand before you and bask in the glory of your victories!
==Rules==
*UNIT HP : Choose units for each battle wisely, for Unit’s HP will carry over from each battles.
*BONUS HP : Some Leaderskills and Arena Battle Conditions will imbue bonus HP to your Units. These will be reflected on the HP bar as an additional portion added to the Units’ HP bar.
*BB GAUGE : The BB Gauge will start at 0 for each day and any remaining BB will carry over to the next battle!
*DOWN UNITS : Units that are down will remain down for the day only. They will not be able to participate in any more battles for the day, unless resurrected with gems or Revive Potions.
*POINTS & REWARDS : You can get ranking rewards as long as you have participated in battles and obtained ranking points.
*SAME POINTS : In the case of two or more players having the same ranking points, the first player who achieved the points will be ranked on top of the others.
*ENTRY & END TIME : Summoners will be assigned to different groups where they will start and end the battles at different time.
==Leagues==
The Challenge Arena is divided into 3 leagues:
*Rookie
*Summoner
*Legendary
Start off in the Rookie league and work your way up the top.
Each week, the Top Summoners of the Rookie and Summoner Leagues will achieve promotion to the next higher League, where stronger opponents and greater rewards are waiting!
Get to the Legendary League and reap the rewards that you truly deserve!
But, do take note, as you league up, it does get harder as there will be more opponent's first strike!
==Battles==
You will face a series of progressively stronger opponents. Defeat them to gain ranking points and drops!
Battles will be auto-battle style similar to the Arena. The team who defeated all opponent’s Units will be the winner. You will not be able to progress to the next opponent until the current opponent has been defeated.
If the timer runs out before any squad has been defeated, the following conditions will determine the winner, in order of priority:
#Number of Units
#Total Damage
#Total HP
