What do you think about the duration time ? suggest.

20secs? 10secs? 15secs?

Seems a little freaking over-powered in my opinion.

I'd say 4 seconds at the most. :)
20 seconds is just crazily OP. :straightface: :smirk:

How about we have a spell which allows us to take control of the brain of the defending player 5 minutes in the past, so we can force them to change their base layout for an easy three star.

Oh, it only lasts for 20 seconds.

FAAAAAR TO OP if you really make it 20secs of invincibility.
Just think about it. Throw down 240 archers make them invicible for 20secs and everything around the spell area is gone for sure. In other words you could 3star bases with all archers and 5 invicibility spells.

I'd say 8seconds at max level at most.

Tnx for the opinions... I'n really not sure about the duration. but thanks to all of you. for the suggestions.

I guess 5/6 seconds could be ok, 20 is too much in my opinion. Anyway it's a good idea

Soooo this basically makes the heal spell useless cause this makes them invincible and lasts longer then a heal spell :facepalm:
and is also not effected by inferno towers...
