1 bar heal LB should be a Aoe targeted circle (like sacred soil) that lasts 15-20 seconds. peeps inside circle enjoy status effect immunity and regen at a potency of 100/3 seconds

2 bar Healer LB should be a "lifesteal" from the targeted mob(s) doing about 1/2-2/3 the damage of a dps lb. HP received from the lifesteal gets spread out evenly among (alive) party members.

3 bar LB shouldnt be any different than it is now, but more immediate when cast.
