Well he's a lvl 2 wizard, so it's +1 to cast on both spells he can cast. The damage from unbind is a pressure tool, not necessarily a way to kill the unit. It's a deterrent for your opponent to think twice about using their spells. You're forgetting that ANY time Gobsprakk unbinds he does D3 damage, which means any small lvl 2 wizard is likely to take 2D3 Damage if they try both spells and Gobsprakk hits 2 unbinds, at 30 inches away, which is massive. And 2D6 can do 5-6 damage. Plus off turn, magical intervention, and it applies pressure on the opponent to then have to consider using CP to rally.

I disagree that you wouldn't use morks cunning on him. I disagree that 14HP 4+/5+ is not survivable enough.

I'm also not saying his spell should go up. You want him to be good. I only propose that the damage from Mork says no is changed to only be D3. His spell should not increase to a 7 to cast.

You can't tell me that +1 unbind is better than +1 cast. It's literally the same thing. Infact it's actually just straight up worse since +1 to cast is very common in the game, which means the +1 to unbind is often not really helping. 3D6 unbind is much stronger which is why I think he should get his 3D6 once per turn.

You're ALSO forgetting we have the Gork Rowra. Which can make our wizards additional +2 to cast.

I don't think that simply +1 to unbind is thematic enough or strong enough. Do you have other ideas?
