From wizard tower level 8,ice wizard should be added in wizard tower
From wizard tower level 8,wizard tower should have an ability to adding ice wizard with loading cost..like x bow,inferno tower...
When ice wizard will be loaded in wizard tower,dps of wizard tower will be reduced..and the wizard tower will Freez the enemy troop for 0.2 sec.....
The ice wizard loading cost should be started from 30k gold per each tower...
When the wizard tower is not loaded,it will be in normal mode...but every time when it will be loaded, a ice wizard will be appeared on the wizard tower instead of normal wizerd...
Such as
Wizard tower Level 8:
Dps:48
Ice wizard towar level 8:
Dps:32
freezing troop per attk for: 0.2 sec
Loading cost:30k gold
I think this will be great...to get ice wizard tower ability from wizard tower level 8
