How to harvest dark elixir faster [TH7]
If you are finding it painfully slow to accumulate 10000 dark elixir to build your Barbarian King, then here's a simple tip that will speed it up a bit: Attack or go through your Defense Log and look for someone who has a lot of dark elixir available (at least 500 or it's not worth it), then drop two level 4 Lightning Spells on the dark elixir storage. You can then try to steal their elixir and gold, but it's probably better to save your troops and just surrender immediately, as they will likely be much stronger than you. On average, I steal a little over 33% of their available dark elixir this way, all without expending any troops. Using this strategy will save you days if not weeks of harvesting -- I guarantee it.
