You can cast Leap of Faith on a sapped, frozen, etc. target.
This is so fun and helpful in PVP! gem yelled “get me out of here,” so I ran over to heal her. Then I realized exactly what she asked for, even though I think she meant for me to come heal her, so I broke my cast and life gripped her to safety. It seems like a good way to save someone, at least temporarily, from rogues. I’ve also enjoyed using it to help speed the flag carrier on his or her run or to remove him or her from a combat zone.
I’m loving this skill.
