Unkillable.

A lot of people may not notice, but for the few people who have encountered this in one of their games, they should know how OP it is.

You should make it that shields dont stack 100%, but theirs a limit of how much bonus shield they can get (per level?) or if someone shields, the second shield is reduced by like 20-30%?

Not sure, but check it out. It's just annoying to deal with.
