I went 5-0 at the LoneWolf GT in dallas last year using a Metal Slann. The Metal lore has it all.
6. Final Transmutaiton is an effective bunker buster and is the same against all armies. Dwellers does poorly against high strength.
5. Lead, a -1 to ws, bs and armor saves is always a welcome event. might not raise the score they need to hit you but can make you saurus and Krox hit on 3's
4. Golden hounds, a character killer, the Look out sirs can make it a unit killer. no armor saves ( Cast it on a Bretonian Damsel whoi LOSed onto Grail Knights) Great stuff on anyone by them selves
3. Robe, hand out the scaley skin to your skinks, the SKROX unit now has a 4+ save and a parry to the front.
2. Blades, +1 to hit, magical attacks and armor piercing, what is not to love, use with lead to hit on 2's, have a wraith problem, no problem
1. lowers armor save, what more needs to be said steam tanks< etc.
X. doom D6 or 2 D6 hits with no armor save
The spells are good. but the lore ability of wounding on the armor save is bad enough to turn folks against it. It can be seen as a self comping pick to use metal. I will say that Focus of Mystery is required. That way you can pick the spells needed. I would hate to be facing demons with only the DOOM available. The funny part is when the chaos or Brett player askes which lore and then gets all sad. Against wood elves, the blades ruined his plan to fight using the dryads. VC wraiths run froma Skrox unit with blades.
