The ice tower

Hello this my first posts in coc. I hope the new tower and troop can make more funny.
the ice tower I believe that it is not the first time have someone think it out.but I observe the coc haven't any tower will affect the troop fire rate and the speed.
The new tower I call it the freeze tower.
the ability of the tower is reduce a group of troop fire rate and reduce the speed of troop.
it is a very powerful defense tower.
I will set up the size will be as some as the hidden tesla.
but the freeze tower will not have the hidden ability.
the freeze tower only have 1 in lv8,2 in lv9 and 3 in lv10.
the freeze tower will have 4 level.1&2 in lv 8 , lv3 in lv9 and lv4 in lv 10.
the cost will be lv1 100w,lv2 300w,lv3 500w,lv4 700w.
The day costs is 4/6/8/10.
the ability at each level
reduce troop fire rate 5%/8%/12%/15%
reduce speed 4%/6%/8%/10%
damage per second 10/20/30/40
damage per shot 13/23/33/43
tower fire range 7

The troop will be design in tomorrow.
