Here’s an excellent spell review from Espace’s Slann Party 2012 blog. http://paint-hammer.blogspot.co.uk/2012/06/lore-of-beasts-party-slann-2012-slann.html I would like to add some things. First, Espace only covered Slann in Temple Guard blocks. Beasts opens up the possibility of running a lone Slann that can actually fight. I’ll admit that would be a risky endeavor. I haven’t tried it myself, but I intend to at some point. If anyone who actually tried it has any insight on a lone Beasts Slann, let me know. Second, a Skink priest can be used to aim the Amber Spear for a nice rank penetrating sideways shot. Third, with Skink priests now able to take Lore of Beasts, you can use a Beast Slann and a level two Skink priest to give you a 100% chance to give the Skink Transformation of Kadon if you roll the Slann's spells first. High Magic Slann and WD Slann Beasts has one of the best signature spells so a WD will probably get a lot of mileage out of the signature spell Beasts isn't the best lore to dabble in for a High Magic Slann that likes to swap but it isn't bad. Wyssans is a great spell and you can be guaranteed to not do worse than that spell. Flock of Doom is good if you are facing low Toughness chaff units, Amber Spear is good If you are facing well armored foes (especially cavalry in a line), and the Curse of Anraheir is a good counterpart to Wyssan's. I like Wyssan's but if I have a Skink Priest with it, I don't see a reason to double up on it with a Slann having it too. Most Battle Reports I've read that try this have the Skink Priest doing nothing at all and that's a waste of points.
