Well back to the original poster, its always worth searching for blood sites if you are a blood nation. Well rare they are usually very powerful. I got a 40% blood site ( or thereabouts) in MP as MA Abysia, I was casting Horde from Hell for fun, cost about 27BS rather than 44BS (approx.), I quickly ended up with 1,000 imps and 40 devil thugs. That 1 magic site alone could well have won me the game.
Sadly, the hosts computer got nicked and the game ended before I could fully exploit the site.
