The breakpoints for the blood and death are 4,6 and 8 and 10 points in the respective paths.

4 blood gets you a 1 blood caster/priest for 12 slaves.
6 blood gets you a 2 blood caster who is also either a wizard or witch for 30 slaves.
8 blood gets you a fallen angel for 88 slaves and some research.
10 blood and 4 nature lets you cast Carrion Woods for 90 slaves.

4 death gets you a necromancer, who is a wizard/undead priest 1 for 12 death gems (he's not a heretic and has ice power rather than fire power and slightly different magic). This is a notably better deal than a specter. He's not inanimate or ethereal or anything though.
6 death gets you a risen lord, who is a passable thug/(inanimate) undead priest 2 for 30 death gems. This probably a better deal than a mound fiend, wraith lord or bane lord, but that depends somewhat on your bless.
8 death lets you summon a risen bishop, who is just an inanimate undead priest 3 and only has the one job, for 20 death gems.
10 death and 4 astral lets you open the soul gate for 90 death gems and some research. The various spectral legionaires are replaced with spectral versions of the common national infantry. Enjoy.

If anyone objects I won't add this stuff - I don't intend to use it on my pretender and I'm still playtesting it a bit.

I'm going to post a revised mod wednesday, and start the game Friday or so?
