Last time I checked all stickmen suggestion where rejected. But I do, like this idea.
1.Make it immune to what ever elment it has. No.
2.Change it so it can lock in an element. No.
3.Make it so it doesnt fly up with damage. Maybe
Stickmen shouldn't be immune to every element or lock an element.
Also they shouldn't be immune to virus, unless soap is droped on them.
i think that if stickmen are in water for more then 10 seconds they should drown
