Here are a few tips which should help you build a stronger defense:
- Test your own defense. There is a sword-shaped button on the bottom of the screen while viewing your own defense. Use this button to play against your own defense. Testing your defense is completely free, you can even resurrect and use Invocations without spending Ambrosia or Gems. Keep in mind that the people who attack you often have a lower Ascension Level than you. This means that your defense might be harder to beat for them as it is for you.
- Regularly upgrade your towers and barricades. The maximum level of each defensive structure increases each time you upgrade your Heroes' Temple. Even the most clever defense will fail should you not upgrade it every now and then.
- Rotate your towers. Press the rotate button at the bottom of the screen to rotate the tower you currently have selected. Some towers are much more effective when rotated towards a certain direction.
- Configure defense waves. The Guard of Thanatos allows you to configure which units appear in the waves that attacking players have to fight while trying to beat your defense. Upgrading the building increases the number of waves, the time between them and how often you can upgrade each wave. Upgrading waves increases the morale points you can use to spawn more powerful units.
