Wu - Isarnia - Lianna - Gadeirus - Little John
Full buff to use (non-green): (1 + 1.85)/0.56 = 5.089
Full buff to use (green): (1 + 1.85 + 0.48)/0.56 = 5.946
Yellow tiles fully buffed: (707 * 5.089)^1.35 = 63193
Blue tiles fully buffed: (797 * 5.089)^1.35 = 74288
Green tiles fully buffed: 2 * ((741+729+618) * 5.946)^1.35 = 672774
Board damage = ( 63193 * y + 74288 * b + 672774 * g) * 0.68
Average damage rating per tile = (63193 + 74288 + 672774 ) * 0.68/5 = 110194
^^Adding Gadeirus really helps!
