New Spell :Invisibility Spell

[ManangatChosen]

Hey guys so I'm new here and I'd like to share my new spell idea.

Invisibility Spell

Effect:Invisibility on Towers(e.g Archer Tower, Wizard Tower, Inferno Tower) and Traps(except Spring Traps)
Duration:5 seconds(Effect is immediately removed once troops leaves the ring of spell

Just in case this is added in the game the devs will take care of the cost on upgrades.

Lvl3:Troops get extra 3 seconds of aftereffect
