Compare to Otyugh, then increase cost.
I did, but this requires 2 elements making the current cost ok.
Close but not quite
requiring 2 elements does not give a -2 cost reduction. Only -1.
So final casting cost of 5|4 would be balanced.
5|4???? GEEZUZ. that would be op. as it starts, it already has some attack, so you should increase the cost.
and i think leaving the cost the same would be good because of the hp increase
