Immunity Core (MAX)
It takes 22 off the chance of every ailment a skill tries to give the Nexomon wearing it, as the Status effects page explains.
A Nexomon wears up to four cores, which you fit from the team menu. Fitting one uses it up from your bag, and cores of the same kind add up. Wild Nexomon on the Abyssal maps sometimes wear one too.
