The challenge system offers you the opportunity to increase your fighting gains (drops and XP) if you fulfill the set conditions. When a fight is started against a group of monsters, you will be given a challenge at random — two if you are in a dungeon or arena. Challenges are completely optional, you can choose to either complete both, one or neither.
Challenges requiring use of spells appear only if someone in the fight has the required spell (Roulette for Casino Royal, Cawwot for Gardener, etc.). Mob-size bonuses are calculated on the number of monsters minus 1.
Glyphs, poisons, and summons' damages and debuffs count as damage and debuffs done by the caster/summoner. This means they affect challenges such as To each his pwn and Keep moving!. Their HP does not count as part of your teams health, and so are unaffected by challenges such as Contamination, Untouchable and Survivor.
Challenges apply to all group members — each member must fulfill the set conditions for the challenge to be a success.
While challenges are randomly assigned to teams, there are some monsters where certain challenges are impossible to get (notably Scanty on most bosses). Should a team die in a dungeon the challenges of their last fight are saved for 24 hours. If they attempt the fight again within that time, they will be assigned the same challenges (however, the targets of challenges such as Elitist, Unwilling Volunteer or Contract Killer are not saved and assigned randomly every time).
Currently the possible challenges are:
|Arachnophile||Summon an Arachnee each time the spell is available, for the duration of the combat.|
|Barbaric||Attack once with a weapon a turn.||Fails if a character does not inflict damage to something with a weapon during his turn, though spells may be still used.|
|Blitzkrieg||Whenever an adversary is attacked, that character must be killed before their next turn begins.||Fails if you do indirect damage to an enemy but don't kill them before their turn. Does not fail if an enemy is damaged by their allies but not killed before their turn. Bribing or healing a monster that received damage will still fail the challenge on its turn.|
|Casino Royal||Cast the spell Roulette each time the spell is available for the duration of the combat.||If the Ecaflip dies, the challenge won't fail for upcoming turns. However it may fail if the Ecaflip dies at the start of their turn, as that results in not casting it when it's available.|
|Clean hands||Kill all monsters without dealing direct damage for the duration of the combat. Traps, glyphs, poisons, pushback damage, reflected damage as well as attacks by summons may all be used.||The challenge does not fail when direct damage is dealt to an oponent, as long as the blow is not fatal. Rogue's bombs do not fail this challenge if they're detonated (but will fail it when targeting the monster directly). Whipping summons will fail this challlenge.|
|Contamination||As soon as an ally loses HP, you have 5 turns to kill your ally.||Does not fail if you win the battle before the five turns are up. Does not fail if a summon loses health and five turns expire. Losing BP from Masqueraider's shields will start the five turns, even if no HP are lost.|
|Contract Killer||Your enemies must be killed in the designated order. A new target will be selected each time the preceeding target has been killed.||Does not fail if you kill an enemy summon, no matter which enemy is the current target. Also does not fail if an enemy kills itself.|
|Cruel||You must kill your enemies according to their levels in ascending order.||Does not fail if you kill an enemy summon, no matter their level.|
|Dodgy devs||Finish this fight and you've won the challenge! It is well known that all devs are cheaters.||It is no longer possible to get this challenge.|
|Duel||When a character attacks an enemy, no other character must attack the enemy for the duration of the combat.||Also applies to enemy summons.|
|Elementary, my dear!||Use the same element to attack for the duration of the combat.||Does not fail due to different element damage done by summons.

|Exuberant||Use all your action points before the end of your turn.||All AP must be used in every turn, including the winning turn. Does not fail if a character is bribed.|
|First the mules||The weakest mule must finish all enemies off (that'll teach you to 'mule' like a Lousy Pig).||The "mule" means an exceptionally low-leveled character. This is a variation of the Low levels first challenge.|
|Focus||When an enemy is attacked, they must be finished off before any other enemy is attacked.||Non-damage spells (e.g. Clumsiness) do not fail. Fails if you hit an enemy summon after another enemy or summon has been hit. Will also fail if you hit another enemy after hitting an enemy summon.|

|Gravedigger||Summon a Chaferfu each time the spell is available, for the duration of the fight.|

|Impertinence||Finish your turn on a cell adjacent to an enemy.||Cannot fail on the winning turn; the final blow may be made while not adjacent to an enemy.|
|Incurable||Do not regain any HP for the duration of the combat.|| Casting Furrow (Swashbuckling Bandit spell) fails the challenge even if you don't heal. |
Stealing HP does not fail the challenge. Hitting a Tree of Life does not fail the challenge. Bloodthirsty Madness fails the challenge.

|Self Sacrifice||Characters must not be healed during their turn.||Can heal others, just not self. Stealing HP does not fail the challenge. Regenerating Word, Cawwot and Sylvan Power fail this challenge. Allied summons starting on a Cawwot glyph fail it too.|
