Item or Monster rarity can be Normal (grey), Magic (blue), Rare (yellow) or Unique (brown). As a general rule, monsters increase in difficulty depending on their Rarity.

Basic Jewels do not affect nodes in a radius. Basic Jewels are Rubies, Emeralds, Sapphires and Diamonds.

Some methods of item crafting guarantee that a specific Modifier will be crafted onto the item. An item can only have one Crafted Modifier, but they otherwise behave identically to other Modifiers. Crafted Modifiers are displayed in a lighter blue colour than regular Modifiers.

Maps containing a Delirium Mirror can have the mirror walked through to unleash the rolling Delirium fog ring across the current area. You must stay within this fog as it expands to maintain the Delirium or it will disappear. Magic monsters are able to gain Delirium specific Modifiers while inside the fog. Rare or Unique monsters in the fog may manifest Delirium Demons. Manifested Delirium Demons inhabit the monster's body to occasionally use Skills of their own. Fractured Mirrors may be found within Delirium Fog, summoning extra monsters while Fracturing Mirror Shards are found at set depths, with more varied rewards. Defeating Map Bosses has a chance to summon a Grand Mirror on a nearby map.
