Item (Risk of Rain)

Passive Items
The majority of items in Risk of Rain are equipped passively. They do not appear to have a stacking limit, however some of their effects seem to degrade. For instance, if you acquire a Monster's Tooth, an item which gives 10 HP on kill, then obtain another, you will receive 15 HP on kill. Further testing is needed to confirm the formula for item effects.

The Current List of Passively Equipped Items is as follows:

Damage increase/Addition.

 * Does not increase chance to proc effect.

Healing/Damage Reduction

 * - Effective up to 9999 HP.
