Combat Ingenuity (an upgrade coming out in the Reanimate Archers box) says:
"The number of [surge] that precedes your [surge] abilities is reduced by 1, to a minimum of 1. This does not affect [surge]+ abilities."
Ardus, either as a unit or upgrade, says:
"[Melee Attack Only] Add 1 white die. This attack is treated as having the surge abilities (both [melee] and [ranged] of allies at range 1-3)."
If Ardus is at range 1-3 of a unit of Archers with this upgrade, is he treated as having the ability as written on their card, or the ability as modified by their upgrade? In other words, does he need one surge or two in order to give his foe a blight token?
