As Battlers win arena battles, they receive an additional Victory Aura buff which can be stacked up to 5 times. The buff lasts for 1 hour and the timer refreshes upon a arena victory and is halved upon an arena loss.
The buff increases the battlers ATK and HP with every stack and at higher levels, even increases the Arena Rewards that the battler receives when they win an arena battle!
When battlers refresh their opponent list, they should defeat the weaker opponents first so that they get a few stacks of the Victory Aura buff for an advantage when facing opponents that are of similar strength.
As battlers do not lose any stacks of the buff when they lose an arena battle; since only the timer of the buff is halved, battlers can choose to fight the same opponent again if they were close to winning.
