The Policy choices you make will affect the earning of this achievement. After each tower you complete, return to the town to see a short message about what has happened in your absence. You can then choose how to respond to the situation. To earn the achievement, play as a druid. Release enemies into the wild so nature can deal with them when possible. Choose policy choices that involves not affecting with nature or side with what your druids want to do.
Collect all 45 unique Bestiary Cards from regular creatures and Bosses to earn this achievement. Bestiary Cards are obtained by picking up the scrolls which the creatures may drop after they are killed. This may require farming Boss missions until their scrolls drop.
Kill a total of 1,000 D'orcs in the same city in Conquest mode. Any of the four different types of D'orcs will increment the counter.
Have your Town Hall at level 3 to make Druids available for recruitment there. Recruit five of them, either all together or over time. Scouts cost 75 triads and 5 food to maintain, and require a population of at least 400.
Successfully complete the game under the Easy difficulty setting.
Each achievement requires a different difficulty setting (easy, medium, and hard, respectively). Once the final Boss and Tower 50 is defeated, it will be earned. Getting gold flags on each tower is not necessary. Replay previous levels with wide open towers to collect triads. Your resources will continue to accumulate even when not playing the game. When possible, briefly start the game to collect resources from the lumber mill, foundry and farm and exit. Before starting a difficult level, consider recharging your spells by playing through an easy previous level.
Select your Town Hall to access the option to purchase Farmers at the top left corner. Purchase 20 Farmers to earn the achievement.
Triad runes drop during combat, in your tower. Create a match of four runes in the same row to create a triad. It will remain on the level until you click to collect it. Try grinding wide open towers, such as in level 26, "Chemer" to do this. Triads are used to get currency for your town. Note: Other combinations of runes will create healing runes, bombs, and super bombs.
You must get a gold flag for all 50 towers, including the Boss towers. To get a gold flag you must finish the level with your tower at full health. Using at least one healer (High Priest recommended) is required when trying for gold flags, especially when going up against a Boss which fires projectiles. Keep the Healing spell ready in the event that your tower takes damage. If your tower is still damaged towards the end of a level, use dummies or barricades to keep the last enemy at bay and wait for your healers to restore the tower before killing it to end the level.
Get access to the Infinity Tower by completing the game. Once you get past tower 50, the Infinity Tower will appear on the Conquest map as tower 51. You have to reach level 10 or higher in the Infinity Tower to earn the "Master Beater of the Tower" and level 25 or higher to earn the "Master Beater Forever" achievement. Use the upgraded Scout and Master Healer. The Druid and the Stone Thrower can also be selected. Stock up on barricades and bombs. If you lose in the Infinity Tower, you will have to start all over from level 1 again.
