I played the Cry Havoc lore card with a lvl 3 Warrior (+2d, lore rolled scores hits). I also ordered my Troll with a Leadership card (9d!). He had one hit point token. I rolled 3 lore in the attack, plus 2 red banner hits (killed a Red Infantry). Can I use any of the lore from my roll to heal the Troll (regeneration), or can it only apply as hits? I suppose this question also goes for other creatures' powers with the Cry Havoc (or Enchanted Mass Might) card, as well.

It would be good to have this answered in the Lore or Creature Compendiums once those are up and running here, but I think it is pretty straight-forward that if Cry Havoc or Enchanted Mass Might are played, lore rolled that turn will count as hits and not be able to be used otherwise. It is certainly the case that lore rolled by a "normal" unit is not able to be collected, even if they are "extra" hits.
