| Oblivion Staff|
|Deceptively hidden as an ordinary quarterstaff, it is actually very powerful, much like the Eldritch who originally possessed it.|
- One Oblivion Staff grants a total of 10 attack speed, 110 mana, 0.4 (+ 75%) mana regeneration, 0.71% spell damage and 10 (20 to intelligence heroes) attack damage.
- Heroes who intend to build a Orchid Malevolence will usually buy an early Oblivion Staff.
