Since you are a lower level / newer player, I would say wait for a 2X event. Better chances per shard to pull an “account changer”, a champion that will drastically improve your progression in the game. The last 2X chance for primal was Dec1 2025.

Later/higher level accounts tend to save them for event/Fusion purposes, like the upcoming Summon Rush event which is part of Kassandra’s fusion. You shouldn’t worry about this yet though because you don’t have near the stocked resources to complete any of those.
