While it's disabled by default, if you enable it... you're pretty much immortal since it has no delay unless you get hit by attacks that bypasses iframes. Maybe it could be "SECOND_IN_TICKS * 10" which I assume is 10 seconds? The delay could be configurable if that's too low or something.

Looking at the config for Bless it's 200 so... that would be 10 seconds then? I'm trying to figure this out so I dunno if that's correct.
