Amount of RNG required to get an item to unlock seal feels demotivating. May be a system where after certain tries it increases your chances to get the item (i.e dreaming city ship). the number required could be high. forr example if you dont get the ship after 15 shattered throne runs petra unlocks it. then I'll know if my rng is bad I can still consistently work towards it. other then that it was fun trying to unlock the seals.
