My attempt at recreating spider mines.
Initial unit burrows to turn into the variant with goblin land mine, when it dies by itself it creates the variant with movement that target's the closest unit in range with kaboom!
@Devalut ah, the other way around, making mana shields and mana/energy to be something hidden. Right, since both ideas (bar shields and mana shields) would require damage detection. However, it would distract the Warcraft III player too much from the known UI stuff. Something added would be better than something changed.
