Terror Frenzy vs armor of caines fury

Action is blocked, acting vampire plays terror frenzy. Blocking vampire plays armor of Caine's fury. Does armor cost extra blood?

Terror frenzy
[ANI] Only usable before range is determined. Combat cards cost the opposing vampire an additional blood this combat. A vampire may play only one Terror Frenzy at superior each combat.

Armor of caine's fury
[val] Only usable before range is determined. This vampire may prevent 1 damage from the opposing minion's strikes each round. Frenzy cards cannot be played on this vampire; cancel the effects of any Frenzy cards that have already been played on this vampire this combat.
[VAL] As [val] above, but this vampire may prevent 2 damage from the opposing minion's strikes each round.

Yes, because the acting vampire has impulse to play combat cards first.

Edit: Armor just cancels the paying for subsequent cards.

Now I believe you are right, but still.
