No Errata
Q: If my Champion has the Deathly Charge upgrade, and makes a Charge action, does the +1 Damage apply to their Attack actions with a Range of 1 or 2 for the rest of the action phase (e.g. if the Champion later makes an Attack action from Ready for Action)?
A: Yes. Note that if the Champion makes another Charge action later in the phase, there is no additional modifier from Deathly Charge.
