Revamped blood collection?

That's not correct since blood slaves have uses for many nation commanders. Blood slaves work great for fully decked out assassins which carry an ethereal bow or a wand of incinerate. The target enemy has been known to spend a turn killing one or two blood slaves thus allowing any equipped items an extra turn in killing the enemy.

Ok, that's another use, but it's also one that's much less work to manage than having to go and individually put slaves on all of your sacrificing priests as Mictlan.

Blood slaves for commanders in battle also work great for spells such as rush of strength, hellbind heart, summon imps and so on. Also for the few special commanders which need guards adding blood slaves makes them also more difficult to kill.

Spending 7 slaves to get a single devil would probably make them even harder to kill.
