Large zombies and Wheelchair zombies attributes need nearly 70k per attribute level to be learned (and increases in price with levels). And they can be learned at max 50 times each.
Those zombies aren’t that much better and some even argue wheelchair zombies are worse than normal zombies since their auto attack is slower.
I think this price is completely unecessary and could be lowered to 1/10 the amount of silver (so nearly 7k silver at level 1).
