After using most of the transform and aura type mementos
- Almalexia's Enchanted Lantern,
- Wild Hunt Transformation,
- Storm Atronach Transform,
- Dwemervamidium Mirage,
- the new Mariner's Nimbus Stone,
- etc,
collectibles in the Personality and Tools categories are unusable until the cooldown for this memento ends, even though there is no cooldown shown on those.
Other types of mementos don't block switching Personalities, and other collectibles are not blocked while Transforms are active.
Also if you log out while a Transform or Aura is active, the cooldown passes but the effect remains, so you can stack the visuals with other memento visuals.
And once again we are coming full circle, transforms and auras should be made into a different type of memento that can be toggled, instead of making it a spammable with an arbitrary cooldown and duration:
