Based on some of the advise on the Forum, I started farming with one hit maps and using all my level ups points on Hero Strength points.
I am game level 50 and 52 Hero Strength points and I still can only one-hit monsters at the Temple of Abaad map. This is even after improving my Hero Strength from 48 to 52, I still can't one-hit at any higher map.
Am I tapped out on Hero Strength usefulness?
