I'm afraid we'd best only grant one Echo - while the stay at the museum before the placement of the Galah is viable, the forum would've ceased to provide Echoes shortly after the characters stopped receiving responses.

For the Echo, would you prefer the high jumps, or the healing spells? If the latter, would it be acceptable to grant it in stages (I would assume we'd have to start with simply Cure at this point, and grant Cura and Curaga with a later Echo), and what would the effects and limitations be like?
