BoH is a much *BETTER* blood summoning nation than vanilla Aby
... But it doesn't have those nice big Abysians badasses infantry and Demonbreds.
Additionally for BoH the Salamander and Dragon mages/priests becomes capitol-only, so you end up weaker in Fire and Holy.
OTOH the sacred GoP are much more useful than the LW and their horrible encumbrance
Overall a nice but very blood-oriented theme. It screams for getting quickly indy mages/sages sites, but somewhat less loud than vanilla Aby thanks to the cheap sacred mages
