Cleric summoned hammers?
 

Do these have bane damage on them on green?

bane damage isn't in classic thru velious and will not be in effect on this server.

I noticed it says they aren’t magic, so do they even hit undead like ghouls?

They were magic in the beta - that's one of the whole points of them. Was that removed?

They are supposed to be magic afaik.

Confirmed they are magic at least the lvl 9 one is

I'm positive that on live the hammer from the spell cast by the Initiate Symbol of the Tribunal (ie. Hammer of Wrath, Cleric 9) was magic ... because I personally used it as my my main weapon (against wisps) for several levels.

BUT ... I didn't start playing until Velious. Still, it seems strange that they'd be magic in beta, not in classic, then magic again in Velious.

Yep, just double checked it against a wisp. Magic.
