Divine Champion: Critical Hit Refresh doesn't activate on a kill

[In Sorrow We Trust]

Summary:

When issuing a critical hit, the Divine Champion should usually extend their Wrath Duration while in Divine Wrath. If the critical hit instead kills the target, the Divine Champion receives no refresh whatsoever.

Expected Result:

1. Cast Divine Wrath.
2. Fight things.
3. Kill something with a critical hit.
4. Regain duration based on the weapon you're using.

Actual Result:

1. Cast Divine Wrath.
2. Fight things.
3. Kill something with a critical hit.
4. No duration is gained. However, if the critical hit does not kill, it will regain properly.
