smoke screen

I was thinking this could be the next spell as you can can see below

Th lvl 9 - air (lightning spell) was 1
Th lvl 10 - fire (rage spell) was 2nd cause fire is hot and raging
Th lvl 11 see my idea water/ice - freeze spell
Th lvl 12 would be light as of - healing spell
Th lvl 13 would be ground - jump spell (defying gravity).
Th lvl 14 would be then - dark following the element trend.
And the lvl 15 maybe metal

lvl 1 black out or smoke screen spell

radius being 4 tiles
seconds lasts 3 seconds
if a troop leaves area 1 second before it is targeted
time to make 1 hour
spell factor lvl 6
The cost is 30000 elixir

At level 2

radius 4 tiles
seconds last 4
". "
" same as above time"
" same as above "
the cost is 35000 once upgraded
Upgrade cost is 1,000,000 + what ever the freeze spell costs to upgrade to lvl 2.


What name sounds best? I thought that smoke screen sounds best as it is more medieval.
