Alternate suggestions for Living Dead

There should at least be a visual effect over the the user. Like the grim reaper standing over the player who has 10 seconds counting down before he takes his life. That way the healer can see that the user needs to be healed.

Personally I like the Dark Soul Cooldown more, to change it a bit:

Beyond Death: Erect a magical barrier in which when you stand in, attacks that bring you past 1HP will not kill you for X seconds. When the barrier fades, stepping where the barrier was, will result in a KO, lasts for 10 seconds.

I do kind of like the idea of a tank invuln which creates a "Safe zone" on the field for a few seconds which then turns into a "not safe zone" for a few seconds. To make it interesting, you could make the "not safe zone" also deadly for any party members that step on it. So you would have to make sure you don't put it on a spot that people need to stand on for a mechanic.
