Exalted Essence.
Opinions on the following as a personal mode to the charm in the picture:
The exalt helps men overcome grievous injuries. Through a venture with three obstacles and a time scale of three scenes you can increase the size of a Battle Group by 1, if the groups size has recently shrunk due to losses in combat.
Do you feel like it's too strong, or too weak? At the moment it's pretty much the equivalent of a recruitment venture. Not sure how strong it should be as a personal mode, and as far as I'm aware there's no charm or mode dedicated to "healing" battle groups.
