H3AD-5T v2

The H3AD-5T v2 is a legendary item in Risk of Rain 2.

Its name and effects reference the "headstompers" from the first game.

The wave can be powerful for early-game characters. Despite not being mentioned in the effect text, H3AD-5T v2 negates all falling damage even if its active skill is cooling down. The additional jump height, however, only takes effect when the equipment is charged.
