What's the timing of Strife removal? When Invaders have reduced Health per Strife, do they get it back before damage is dealt?

The Strife is removed before they deal Damage (JE rules p. 7, Ravage Timing sidebar). This means that if their Health is reduced by Strife (via effects like the Panic Fear card) they get their Health restored first.

This matters if Dahan are dealing damage simultaneously to Invaders, with powers like Words of Warning or Why Don't You and Them Fight.
