But WHM has everything!

Takin inspiration from ideas in this thread and other FF titles...

I like the idea of an "Full Life" spell that raises someone at full health.

Also an "Auto Life" status/buff that casts raise on someone if they die.

"Reflect" would be a fun--cast it on a people that don't like to dodge, indirectly shield them from some damage and then do some back.

Spells that sacrifice your own health for others would be interesting but I'm not sure I see the utility... Someone is still going to be low on health and need a heal. Why not just cure? Unless it's a free cast and a larger heal (i.e. Bigger than a Cure).
