Bullhorns are items instantly call 4,000 Farmers to your reserves to allow for more Troops to be trained.
Bullhorns have diminishing returns. Just like Energy Packs, the more you use in a short period of time, the less-effective they will be, and grant fewer farmers. Once you have Trained over 3 days of Troops in 24 hours (~21,000 Troops), the number of Farmers gained from a single Bullhorn will begin to diminish. At ~20,000 troops trained in 24 hours, a Bullhorn is only 88% effective, at ~40,000 a Bullhorn will only be 75% effective, and at 145,000 a Bullhorn will only be 50% effective.
Bullhorns can be obtained through:
- Opening Atlas Chests
- Claiming Atlas Season Rewards
- Purchasing for 600 Diamonds (if you do not have enough Bullhorns and the game prompts you when training/reviving troops and your current farmer count is not enough to complete the action)
