Diablo's attack is a gravity attack that does the amount of damage of
his level's percentage of the enemies' max hitpoints rounded down to the
nearest tenth. So diablos, on an enemy with 100hp at level 30 would do
30 damage. At lvl 100 it would do 100, but if the enemy had 10,000 hp
it would do only 9999 damage. If it had 35 on that 100hp enemy it would
do 30 damage.
