my mistake with soulblight. i was quite tired when i posted and totally forgot about the powered up version.
Going to 'ard Boys today, will see how two slaan work out. One with light, the other with death. Death Slaan will have a magic carpet and a power scroll, to do exactly what vaalnn said, namely "in summary, if you get a purple sun off and it destroys 1000pts of your opponents force, wel done, you're an ass hole." Its 'ard boyz, and if the sun gets out of hand, well, I am creating an I10 bubble with the other slaan. Plus soulblight with lights net is getting a bit on the ridiculous side.
Results: Slaan blew himself up once, and the other guy's army the other two games. Lesson learned? Always pack the +3 initiative potion on the power scroll/purple sun slaan. Crowning achievement was killing 2 stegadons, 5 kroxigors, 15 temple guard, and about 40 saurus warriors.
I've said to people from my store before saurus warriors should be banned from having purple sun cast on them and just generally being exempt from Initiative tests
