In both of my toons i was able to complete the quest and get the xp boost but i have not transformed into a skeleton at all.
I have seen some players in dolmens looking like skele.
What should i do to get a skele costume ?
They changed the way the animation worked after people complained last year.
Using the whistle gives you the xp buff, using the cauldron changes you into the skeleton.
Also note that the cauldron spawns *behind* you, so it's rather easy to miss ...
Spawned from the Mementos menu, it spawns behind
presumably because the character turns to face the camera when opening menus
quickslotting the whistle and using it from there puts it in front
