Whitch one is better ? Or both use their special magic attack that dont need runes and damage is same ? Because iam already shoutig for 3 days and no one sell invadis :/ So maybe zuriel is same

The difference between Zuriel's staff and rod is that with z staff you can cast multi spells, they are both really powerful.

Btw, you need to repair zuriel's staff with ancient energy before it crumbles to dust , when rod hits its level (0) it does not dissapear.

You can look for more information here

Zuriels staff has the multi effect, and has the exact same stats and maxhit as the rod of ivandis. The only difference is that you can sell the rod later, and you can't sell the staff later.

Both aren't really my thing.
I'd go for zuriels if I had to buy either.
Repairing stuff is a bummer though.

They have the same offensive bonuses but the zuriel's staff has a multi target spell and the rod of ivandis only has a single target spell, I would go for the rod of ivandis since it has more charges and is cheaper to repair.
