You will be spawned into a boxed room after chasing the Wizard through the level - Nerve will drop down from his perch and after some dialog will engage you.
Nerve has two phases, his first is melee coupled with erratic dashing and a whirlwind attack that will launch him in the direction you are, use your slow-mo ability to evade this and close the gap after it is completed to get in a few melee attacks or charge attacks if you've taken the skill.
After a certain damage threshold, Nerve will leap into the air and bombs will drop on the area. Avoid these by dashing or circling the outside of the room in order to avoid cornering or surrounding yourself with detonations.
Nerve will then drop down and immediately dash to you, so use your slow-mo ability again and repeat the cycle.
Consistent dashing and use of slow-mo, alongside a strong melee weapon (use supply drop) and Nerve should go down without too many deaths.
