You need to re-equip all your gear if you die while shifted btw. Othwise you won't gain anything from your gear.

All Malar's shifter faithful are gone anyways. they lacked clerical guidance!

Quick question,
if a shifter is in a particular form and dies, does he revert to his original form in death or does he retain the form he's in even in death. and does this apply to the thousand faces widget as well.

To answer your question: if you die while shifted into say, a dire tiger, you do revert back to your 'natural form'. If you die while under the effect of the One Thousand Faces widget, you do not change back into your original form. You stay in your sneaky disguise.

Aaand as a 30-seconds-later-edit, I totally ignored Dead's response, so you can just ignore this if you like. I don't know the lore-how behind the fact that you don't change back to your original form from the One Thousand Faces widget skinchange.

Is a druid or a shifter under 1000 faces shifted back to its natural form upon death?

Correct.

If a Shifter/Duid or what not uses the 1k faces widget and gets killed, they would in fact revert to their natural form, even if the widget doesn't auto-swap you on-death.
