Juggernaut Oz Kits have one main point of attention - resistance against up to three different damage types. The damage types include non-elemental, incendiary, shock, cryo, corrosive and explosive.
In addition to their varying elemental resistances, Juggernaut Oz Kits feature the highest slam damage of any type of Oz Kit, and are the only ones where slamming with one equipped will shatter a stunned enemy's air mask.
An enemy that is killed by asphyxiation after a Juggernaut Oz Kit shatters their air mask will not count as a kill made by the Vault Hunter that caused it. This means that the death will not trigger kill skills or grant experience.
