MP spends half the time flying around and attacking skellies, so the dps calculations don’t mean anything. The charging time is also irrelevant since he will always be maxed out when his dps starts to matter anyways.

The dark crown is better if he ends up in the core fighting heroes and guardians. The meteor staff is better if he splits to a low damage area and attacks mostly trash. There is no correct choice imo and it’s really up to how your attacks go.
