Perfect Forest Warrior loses Onslaught buff upon re-entering an area.

I'm using a Perfect Forest Warrior Spectre which should provide Onslaught as an Aura, however the buff disappears whenever you re-enter an area.

Be it after a death, portaling out to dump loot, or upon entering a Vaal Side area.

I'll second and mention that Perfect Cannibals are bugged too as they don't provide the Purity of Fire aura.

Can confirm bug for Perfect Forest Warriors
