Tip #8. Focus on Dark Elixir

Once you reach Town Hall 7 and older, your Dark Elixir resource will be limited. By normal play, you usually run out of all the golden and elixir updates long before you get enough Dark Elixir to maximize your heroes and build Dark Barracks. As a result, you must take care of the Dark Elixir over all other resources, saving spells and units of the hero when you get a big piece of Dark Elixir.
