Titanic Knurl

Not to be confused with Colossal Knurl. The Titanic Knurl is a Boss item in Risk of Rain 2.

The Knurl adds 40 hp for the player, and increases their regeneration by 1.6 hp per second, per Knurl.

This item is only found as a reward for killing a Stone Titan Boss. If multiple players are present or a Shrine of the Mountain has been activated, any combination of an Uncommon item and Knurls may drop.
