2nd campaign idea

the first campaign is there to help you get started and to test new attack stratagies which is nice but recently i had the idea for another campaign in which we verse dark elixir entities that have not taken form yet.

the dark elixir campaign is unlocked at th8? and is staged undergroundthe mission rewards i havent though of yet but i though of a end reward for compeleting the campaign, a red gem.

The red gem is simmilar to it's green counterpart but because it's absorbed dark elixir it's become more powerfull but at a cost. the altar it rest on is a 3x3 structure that does afew things all requireing a sacrifice of dark elixir
ideas so far:
defencive - cost:2,000? - effect: all defencive structures gain 50% more health - side effect: all defencive structures lose half total health
offencive - cost:1,000? - effect: the red gem altar becomes a turret with the following stats
range: 12
dps: 40
RoF: 3s
damage type: single target damage
targeting: ground and air
favourite target: any
- side effect: ???
constructive - cost:3,000? - effect: training, construction, and research times are reduced by 10% - side effect: training, construction, and research times are increased by 15%
side effect happen when the red gem altar is destroyed in combat which immediately triggers it's cool down
all effects last for 6 hour with a 6 hour cool down
