Good staff for a wizard?

[Bloodartist]

Hi, do people know any and all good quarterstaves for a wizard (lich) and where to find them? Im particularly looking for extra spells and abilities rather than hitting people with it (ugh..). Im at mythic rank 8 atm.

I have had Blaze of Disaster for a long time, which is kinda lackluster at the high level... Can cast three fireballs which at high levels is just a gentle tickle.

Feels like I've missed something somewhere along the way..

in ivory sanctum in act 3 you can get the warmaster quarterstaff that adds 2 dc and 4 spellpenetration

in act 4 you can get one good for a evocation mage under certain conditions

and in act 5 you can get one in greybor companion quests under certain conditions

war mage staff in ivory sanctum adds +2 to Dc of all your spells and stacks with other items.
