New Smoke/Fog Spell

[DivinePoet]

Suggesting a smoke screen or fog effect spell that allows troops within to approach targets in stealth, keeping them safe and not locate le by nearby defenses. Can either be located after commencing attack or after a time period elapsed 5 or 10 seconds.

I really like this idea. At 5-10 seconds it isn't very overpowered either
