Even if you were attacked twice a day every day and completely depleted both max-level inferno towers in each attack, you would still only require 2,800 dark elixir to keep them topped up. Your 3 max-level drills each collect 100 DE per hour, which means that as long as you log in somewhat regularly you will collect 7,200 DE without ever raiding even once.
