I found another summoner staff:
The Raven Staff: 37 base damage. It does not shoot projectiles but is fast moving. It does not say if it can pass through blocks. It is dropped by Pumking.It can not see enemies outside it's 50 by 50 sight range. The best Modifier is Ruthless.
Deadly Sphere Staff: 50 base damage. It does not shoot projectiles and is slow. It can not pass through blocks. It is dropped by deadly spheres. It can not see enemies outside it's 40 by 40 sight range. The best Modifier is Ruthless.
EDIT: The ravens can pass through blocks.
