Ideas to get gems faster (on builder base mode)
1. Miner hut
It'll be like clock tower but it will only boost your gem mine even faster then clock tower maybe like 12 gems every hour or however fast you guys think it should be.
2. Farm house
A building that recruits gardeners to plant trees, rocks, possibly gem mines, in your base faster or have a planting time! It would be fun to watch them walk around your base.
3. Add Another Gem Mine
4. Have challenges
5. More achievements.
6. Be able to steal gems from gem mines.
Just like gold mines and elixir collectors, you get to steal gems from the gem mine, but the gems in the gem mine won't be taken away from you.
