10 Video Game Secrets Everyone Knows Except You
2. Kill Undead By Casting Life - Final Fantasy Series
Like most RPGs, the Final Fantasy series has a rock-paper-scissors style of elemental weaknesses.
You can usually count on fiery enemies to be weak to ice, robotic enemies to be especially sensitive to electricity, and undead enemies especially flammable. (It's the dry skin.)
And yet, rarely are you taught that undead enemies have a much more significant weakness: healing magic and items. After all, if a spell heals the living, then it stands to reason that it would unheal the dead. And if it resurrects your party then it also makes sense that it would kill a dead thing even more.
OK, it doesn't make a ton of sense, but you can't deny there's a certain logic to it. What's even better is that many undead bosses throughout the series are just as susceptible to death-by-life as your average zombie grunt. To the undead, your white mage may as well be a walking nuke.
