Oh those are completely up to the GM! Multiple times are no problem!
Nice. Also... does the 'Harm Damage' upgrade apply to basic attacks only, or does it affect powers as well? Or is that another 'GM's prerogative' thing?
As an upgrade it's meant to be basic attacks, but a GM could make it flashier if they want!
Alright, fair enough. Could be a separate upgrade to up Power damage, or could do the one upgrade for both.
