Challenges are additional rulesets that add to the core gameplay experience of Monster World.
There are currently 5 challenges in Monster World as of the pre-release version 1.0.9. These are:
|Overflow||Every time you add an Ability to your Deck, add in 2 additional copies.||This challenge gives the player the same effect as 2 Dark Chalices.|
|The Collector||Start with a Deck that contains one copy of every Ability in the game.||This gives the player one of each Ability their character can use.|
|Infinite Knowledge||Start with the item "Illuminating Pyramid". At the start of your turn, add 10 random Abilities to the bottom of your Draw Pile.||The Illuminating Pyramid allows the player to see the drawing order of the Abilities in their Draw Pile|
|Curse of the Drawer||Whenever you attack an enemy, draw 2 abilities. Overdrawing an ability banishes it. (Maximum hand size is 7.)||This gives the player Greed and every enemy the Drawer's Deceit.|
|Hardcore||Start the run with 5 maximum HP. Difficult and unfair.||The dreaded Hardcore Mode is the ultimate test of a Monster World player's skill.|
Each challenge affects the overall strategy of a run in a different way.
