This spell should be used for your own base. It should be called Heavy duty. It can make Archer Towers and Cannons double the speed that they shoot. I think the spell factory should make spells that benefit your own base. These should cost gold, as attack spells cost elixir.
Heavy Duty
- 40000 elixir
- Targets all archer towers and cannons in your base
- Area Splash
- Archer Towers and Cannons shoot x2 speed
- 1 hour training time
- To upgrade you need a lab lvl 5
- The spell at lvl 1 should last for 3 hours and should have a 30 minute cooldown. Stats increase as upgraded
Just a thought
