[Taqwus]

As has been previously noted, any spell that summons monsters which stick around -- including Carrion Animation and Angelic Host -- is not anonymous. Spells which summon 'Special Monsters' -- horrors, earth elementals -- are unflagged. 'Send Tupilak' is obvious, because there's only one nation which can cast it.

A successful 'Vengeance of the Dead' is, if memory serves, a flagged attack -- if the MR check is made, it's anonymous, but the battle resulting from a failed check is not.


Spells which cause pure damage or other effects not causing a battle, are always anonymous -- to a point. The quirk is that you can get some information from the effect of a damaging dome, if memory serves.
