I think he meant Blood Vengeance, not the bless ability Blood Curse. It's an ability intrinsic to certain units (Vastnesses have it, so do Doom Horrors, don't remember the other Horrors since if I'm going to wish for one I'm going to get a Doom Horror; slightly better stats than even King of the World if memory serves) and available through a Blood battle spell.

Basically, anytime somebody does anything that causes damage to the Blood Vengeance'd unit, the attacker must make an MR check (modified by the blood vengeance ability; Vastnesses and Doom Horrors have +2) or take the damage themselves, leaving the protected unit unhurt!

It's rather cool to see a swarm of missiles sweep over a Horror or Vastness, see most miss, see most get ignored due to Ethereal, then see casualties among the units "lucky" enough to hit.

Incidentally, I now favour Doom Horrors over Vastnesses, although the former requires a Wish. (Note: even for nations NOT playing R'lyeh, you can get Vastnesses without Wishes if you're lucky, since there are other magic sites that allow void summons. I don't think the odds are very good, 'tho. Fear R'lyeh if it finds a second void site.) Doom Horrors get 20 PROT and the Etherealness, Blood Vengeance, similar MR, identical mobility, lack of vulnerability to magic duel, high (well-deserved) scariness factor, and more powerful attacks -- life draining heals itself, and Consume Soul is delicious. They're not sacred, but if you insist just make one your Prophet (!). So it can't bless any accompanying Horrors. Do you really have to?
