My guess would be a re-roll. But that would have to be up to your gaming group. But if they made me keep a spell I couldn't even cast that would be messed up. This needs to be faq'd , as of now you are probably just better of avoiding lore of beasts unless your gaming group is cool with a re-roll.
Once again. This needs to be faq'd. Before the faq update slann was infantry and everyone was content. Now the slann cannot cast a spell that requires him to be on foot, but for no particular reason. And because of the lack of explanation, more questions just keep popping up... Ok. /End of whining.
And since the Steam Tank auto-fails any initiative test the Pit of Shades or equivalent auto-kills it now.
well there's always the wizard's hat for the oldblood if you guys really want to use a dragon. that's if you can roll for the spell!!
I think I would always run him on a cold one since he is going to be stupid anyway and need the armor.
I think the whole turning into a dragon thing is overestimated. Let him turn himself into a dragon on a 20+ He will waste 5 or 6 dice and he takes the risk of miscasting on all those dice. Then, on your next magic phase, just throw 4 dice at dispelling it (need 16).
The nice thing about an Old Blood getting the spell dispelled on him is that he will still be a beast in combat without it
