I save a lot for Lavender:
-A lot of Gems (well, in fact my other Knights don't like Gems...):
(That said I am reaaaaaaally frustrate by the "Encounter with the Red Bloom Dragon" Quest (to Evolve Orchid Mydler) because I cannot get a single 5* Bloom Dragon there, after too many 50 and 80 Stamina runs... I am starting to think these Quests are a real waste of Stamina
.)
