The Anthropus Talismans are used to build the Spectral Ruins,upgrade the Wraith's Altar, and summons your Wrath Dragon.
100,000 Anthropus Talismans are required to start the SpectralRuins outpost.
You can obtain Anthropus Talismans from killing Anthropus using a Great or Elemental Dragon in the march. You may obtain them by attacking level 4 and higher Wilderness, or level 1 and higher Anthropus Camps. Each 500 Anthropus killed will award you with 1 Talisman. The Anthropus kills are not cumulative (they will not roll over into the next battle).
For example: you will not earn a Talisman by killing 400 Anthropus in one battle and killing an additional 100 Anthropus in the next battle. The number of anthropus killed is rounded down to the nearest 500; you must kill at least 500 Anthropus in a single battle to earn 1 Talisman. The number of Talismans won in battle will appear on the battle report.
Another way to obtain them is to purchase them with Rubies, 50,000 Talismans for 55 Rubies. Meaning a total of 110 rubies would be needed to complete the requirements, the price for 155 rubies is $19.90.
Tip: When fighting with ranged units (e.g. city dragons) and Battle Dragons or Swift Strike Dragons, you will lose some Battle Dragon and/or Swift Strike Dragons due to how the battle mechanics work. It is recommended to use other ranged units (Longbowmen, Lava Jaw, Fire Mirror) with your City Dragons. If you must use Battle Dragon/Swift Strike Dragon with a city dragon, use the Wind Dragon to minimize losses, as it has the shortest range.
