Enemies Explode causes some considerable explosions. At its highest (at least according to gameplay, lore is likely much higher), Enemies Explode has a radius of 20 feet (or 6.09600m).
Let's put this through Nuke Map and play around until we have an accurate radius, and with an accurate radius we get a fireball yield of 0.001634 kilotons (or 1.634 tons of TNT).
Final Results
Enemies Explode = 1.634 tons of TNT
