Doppelganger

See also: Legend 49: The Bodychangers, Legend 3: Vendor
Doppleganger corpses were found on Day 94 with 'fake' Vinmira's body near White Beach around the pyre that destroyed Onwen's Holy Symbol, and several more in Onwen's villa Days 87-94 (10-17 May)
'Fake' Vinmira appears to have beeen an 'enhanced' form of Doppelganger - it did not revert to form immediately after being killed, and in fact it was regenerating and had to be killed again on Day 99 Zoom 2020-04-22 21:00. The fake Vinmira was able to duplicate the real Vinmira's scent sufficiently to fool Kirsten - and even Vinmira does not know how to distinguish between real people and doppleganger impersonators.Vinmiras Departure
We believe that several party members had been impersonated by 'nomral' doppelgangers.
DM stated that Dopplegangers are 'legendary creatures' [Reference required]
Doppleganagers also attacked the party around day 97 Zoom 2021-04-08 21:00 in conjunction with some Owlbears. These dopplegangers had spell casting ability - described as 'a mage and possibly two druids', they appeared to mimic the spells of the party - including a 'mini fireball'. However, they also cast a 3-missile MM, implying a level 5 mage.
