Make sure to create your custom cheat sheets to manage your resources better!Just like units, spells are very expensive and take awhile to produce. While they can be very effective, you need to make sure that the battle you are fighting warrants the use of such a spell. You should know that the Rage Spell starts at 23,000 elixir and the Healing spell starts at 15,000 elixir; each time you use these spells, you need to be sure that using the spell will allow you to earn at least an additional 15k or 23k resources (spell depending).
