New spell idea. Please read.

First off let me say I'm sorry for my last post. I gave the idea to my friend and my info for the account and he changed many of the ideas about it. So I will be reposting it with the correct Info along with many of my other new ideas. So without further ado my latest spell idea.

1 name
I haven't figured a name out for it. I was thinking sometime like Hex.

2 what it does
when dropped it creates a black ring of fog about the size of the jump spell, all troops within the ring take only half damage but also deal only half damage. The ring last for 10 seconds. The effects r effected by the lvl of the spell.

3 upgrades
1-50% damage dealt 50% damage taken
2-55% damage dealt 45% damage taken
3-60% damage dealt 40% damage taken
4-65% damage dealt 35% damage taken
5-70% damage dealt 30% damage taken
6-75% damage dealt 25% damage taken

4 cost (all cost r dark elixir)
1- 100 to make. Unlocked at Th8
2- 115 to make. 45,000 to upgrade. 6 days.
3- 130 to make. 60,000 to upgrade. 8 days.
4- 145 to make. 75,000 to upgrade. 10 days.
5- 160 to make. 100,000 to upgrade. 12 days.
6- 175 to make. 125,000 to upgrade. 14 days.

5 other info
The spell only has a housing space of 1 due to it being a dark elixir spell. The rage spell will not effect troops under this spell but other spells like hast and healing will.

6 final notes
All the ideas above r subjected to change. I would really appreciate help with comeing up with a name. And the I would also like thoughts on the duration of the spell. If this does get implemented in the game I wish to receive some credit. Thank u for reading and plz let me know what u all thought.
