Mobs only visible while dead

[wodim]

Not sure if this can be done (depending on where it is stored I guess) but would it be possible to show somewhere in NPC pages when a mob is only visible whilst you are dead? For example https://tcubuntu.northeurope.cloudapp.azure.com/aowow/?npc=6491 or https://tcubuntu.northeurope.cloudapp.azure.com/aowow/?npc=10988

there are multiple sources of this.

Spirit Healers and Spirit Guides are flagged as such and thus invisible npcflag & 0xC000
there are Spell Auras that cause this effect. those will be hard to catalogue.
and the Kodo has type_flags & 0x2 CREATURE_TYPEFLAGS_GHOST set.

eh .. onto the eventually todo pile it goes

Re: auras, for example: https://tcubuntu.northeurope.cloudapp.azure.com/aowow/?spell=10848 used by https://tcubuntu.northeurope.cloudapp.azure.com/aowow/?npc=9299 and perhaps others (not shown because of #224)

Spells such as spell=33900 are a visual effect and do not have anything to do with whether the NPC appears only when you are dead.

Is there any addon that shows the ID of auras and spells in-game?
