@J4m3sR4n0r72 *Nerdy mode on* Maybe the name "widow" refers to black widow, as in a deadly kind of spider. Hence, it is a legacy of spider mine, but made much more deadlier. :P

@J4m3sR4n0r72 well... at least it attacks air unit also, unlike spider mines.

lolol... I'm no starcraft player but I love that entomb skill. Ultimate trolling skill i've ever seen in strategy games. XD
