Challengers

Challengers are skilled fighters that appear in Shadow Fight 2 exclusively to challenge Shadow having heard of his remarkable skills and merely wishing a good fight. Whenever Shadow may encounter any of them, the fight difficulty is always displayed as Insane and the player must get a least few upgrades on the equipment in order secure a win. The Challengers initiate a special mode of fight that works exactly like a single stage of Tournament having a maximum of three rounds timed 99 seconds where the player has the freedom to use his/her own equipment and does not feature any altered rules or conditions. The fight takes place in the location of where the Duels of that Act would.

Upon their defeat the Challengers give up their enchanted weapons to Shadow which he may now use for his battles. Other rewards are fight bonus and small amounts of XP. If the player loses, he will be given two options; one, to simply leave, two, to try again with x amount of gems. For every rematch you will need more gems. The maximum you can pay for rematch is 30 gems. Once a Challenger is fully declined a fight, s/he can never again be resought for the same later on.

Trivia

 * Challenger Weapons always tend to have better stats than the weapons of the level on which the are won because they are readily enchanted.
 * All challenger weapons can be used by other fighters (in the way that the weapons are just re-skins, the only exception is Fisher):
 * The Nunchaku is used by the fighter Soothsayer and her Ninja counterpart.
 * The Naginata is used by Wasp.
 * The Katana is used by the fighter Vixen and her Ninja counterparts.
 * The Kusarigama is used by the fighter Viper, bodyguard Reaper, bodyguard Puma and their Ninja counterpart.
 * The Dadao is used by the fighter Backsword, bodyguard Kraken and their Ninja counterpart.
 * The Candy Canes are re-skins of the Shuang Gou, the latter being used by the fighter Fury and her Ninja counterpart.
 * Seven of the eight Challenger weapons have identical functioning to many of the usual In-stock weapons. Here the Wanderer's Staff stands out for having a different Attack Frenzy than the usual Staves.
 * Since Nova is fought in the Interlude, that Challenger Fight is the only one to reward the player with fight bonus in Platinum coins.
 * For those who have reached Act VII and then be challenged by Festivus, that fight will be the only challenger fight to award fight bonus in Digital Currency.
 * Festivus is the only Challenger (and opponent) to use Festive Special Ranged Weapons i.e. the Christmas-Special Snowballs. Also the duel between him and Shadow takes place in the Dojo, also the only one to be so. It is unknown whether Festivus, being a Christmas Special Challenger, is a permanently available Challenger or will be scrapped in the later updates of the game.
 * Before the Act VI update, Outcast was called Troll.
 * Formerly, Rose was called Lana.
 * Nova is actually a fighter from a group of mercenaries. When you lose to her once it is revealed by the Sensei that the person who sent Nova to fight Shadow is related to Titan meaning that this group of mercenaries in some way or another works for Titan.
 * Most of the challengers are fought before the last level you will have in a certain province.

Tips

 * Fight a lot on Survival mode upon reaching a new Act, as the Challenger usually appears when you reach the following level (Trickster appears in level 5, Hawk appears in level 11, etc).
 * Get massive amounts of money to cover the equipment of the next level, which means that as soon as the Challenger appears you can go to the store and buy all the equipment you need plus upgrades.
 * With that said, every single one of the challengers can be fought on Easy mode.
 * Yes, including Festivus.
