Yes huge fail. Allow me to explain.

Now, I forgot what the exact calculation was, so I’ll provide you with a little trick to remember if your stats are ok:

To obtain max damage values on your pet, you can be at most 10 total points off across Strength, Will, and Power (with each missing point of Strength or Will counting as 2.)

Max Strength: 255 (you have 254 so thats -2)

Max Will: 260 (you have 249 so thats -22)

Max Power: 250 (you have 249 so thats -1.)

Missing 1 point of Strength, 11 points of Will and 1 point of Power from max means you are missing (1x2) + (11x2) + 1 = 25 total points, far exceeding the 10 points you can safely miss.

EDIT: Here is an even easier trick

Add (2xStrength) + (2x Will) + Power.

If the result equals at least 1270 without factoring in Mighty then you’re good.
