Predatory Instincts (Risk of Rain 2)

Not to be confused with the first game's version, Predatory Instincts. Predatory Instincts is a returning Uncommon item in Risk of Rain 2. Whenever a critical hit is dealt, the item increases attack speed by 10% per hit, up to 30% per stack. This effect last a very short time, but can lead to massively increased attack speeds. It also gives a hidden +5% crit chance.

Completing the fittingly named Challenge Rapidfire unlocks this item. Ironically, this is one of the best items for achieving 200% attack speed.

Visually, the item is shown as a feathered headdress atop the players head.
