Boss Icons for their most damaging element.

On the map when viewing a boss icon you will be able to see a lightning, Flame, Cold, phys or chaos symbol under or above their skull. This is for new players to help prepare them as they level through the acts. Espectially in HC for new players. It would also be nice to give some bosses a new symbol if they’re particularly dangerous such as Silverback, Blackjaw and the giant.

The icon can simply be a Skull with red eyes.
