Mictlan, Cross Breeding and Luck

[Bowlingballhead]

Summons are definitely the point of blood magic. Don't let the first couple of summons fool you - fiends and spine devils are not that tough, and bone devils are easily dispelled. It's when you get to third and fourth level that blood magic begins paying off. Devils and demon knights are cheap to summon, the former are powerful units, and the latter dominate a battlefield. I've sent eight demon knights up against twenty black knights, and won. Four or five demon knights will roll over independents.

And blood magic gets some stunningly forgings, too. Probably more items to enhance blood skill than any other magic discipline. Blood stones. The dreaded soul contracts. Slave collars.

And you can cast Send Horror. I haven't gotten to do that yet, but I understand it works now, and I'm... wholly impressed by the power of the horrors I've run into.
