Actually there is absolutely no point in adding vit. It adds a negligible 4-5k hp.With just 2 taos/2 rays, I got up to like 500k hp (1 tao gets me ~150k hp). Plus, no need for skolls since no vit and 2x tao=-100 def.
Additionally since rabbit has 10% demireducts, I can easily get 80-92% demireducts without sacrificing too much for my build.
So the problem is: too much hp, too much reducts, SN hits comparable or better than actual magic classes, and being a baby, 2k extra stats can let me go melee/thana with mammonite, plus they have a cart which gives them extra weight. SN in our current metagame is broken and I'm surprised everyone hasn't quit their current class and is not playing such an OP class.
And addressing this topic, a baby can wear something like Professor Cursed or Creator Curse to up their matk or mammonite damage. Considering that they're already OP, I think this nerf is the first step and on the right track to damping down this unbalanced class.
